What a trade search costs before it rings
The table below puts a price on the click that starts a call: garage door repair clicks in El Cajon averaged $42.13 and electrician clicks there averaged $16.79. The receptionist takes the call that follows, asks only the questions you approved, then books the job or sends the next step by text.
A customer can call from the results page without opening a website. The “plumber el cajon” results we checked put the local listings before the organic links, and a tap on one can start the call. That makes the service list and hours in the receptionist’s knowledge base part of that call.

The El Cajon market
What El Cajon callers ask before they book
The median home in El Cajon was built in 1974, so the receptionist’s answers should cover the repair and remodel questions that come with older houses, in your words, while anything that needs a technician’s judgment goes to a person.
41.5% of El Cajon’s occupied homes are owner-occupied, so the call rules should cover tenants and property managers as well as owners. The receptionist should ask who is authorized to approve the work before it books, and route that answer to the person who can confirm it.

Trades in San Diego County
Urgent calls and project calls need different scripts
A burst pipe before breakfast and a garage door that will not close after dinner both want an answer, and neither wants a form. The call rules should say which of those calls goes to the on-call technician, which waits for the next opening and which gets a text with the address and the problem.
San Diego County's 1,691 residential remodelers work on planned projects, so the call should collect the address, the scope and the timing and put an estimate on the calendar. A landscaping company, one of 943 in the county, follows the same path.

Set up for you
How the phone line gets built
You approve every answer before a caller hears it, and the line goes live only after you have tested it yourself.
List the calls that need a person
Start with a week of real calls: which ones needed a person, which could be booked, and which only needed a text back.
Write your answers down
The knowledge base gets your services, hours, service area and the answers you already give, written the way you say them.
Connect the booking path
The calendar or CRM takes the booking, and a transfer rings whichever number you name for that kind of call. We check the connection before launch.
Listen back and adjust
After the first calls, we go through recordings with you and fix the answer or transfer rule that caused a wrong turn.
What the AI receptionist does on every call
The same eight parts go into every AI receptionist setup, wherever the business is.
- Answers every call, 24/7
- Qualifies the lead
- Books the appointment
- Answers common questions
- Sends follow-up texts
- Captures every detail
- Transfers to a real person when needed
- Connects to your CRM and calendar
Proof
The garage door site and the plumbing phone build
A garage door company called Smart Doors LLC hired Lithium for a new website, then added the AI receptionist to its phone line. The plumbing project in the card beside it was a different build: a custom phone system that sorted after-hours emergencies and sent the details to the on-call technician.

FAQ
El Cajon AI receptionist questions before you call
Still curious?
Call (503) 766-5964 or email [email protected].
What happens when a caller asks for a person?
The call transfers to the number you choose. You decide which requests go straight to a person, such as emergencies or an existing customer, and the receptionist follows that rule. For the rest, the receptionist answers, asks your qualifying questions, then books the appointment or sends a follow-up text.
How does the $179 a month work?
There is one price: $179 a month for the AI receptionist, with no contract, no setup fee and Lithium managing the line. That covers answering, qualifying, booking and follow-up texts. You can stop whenever you want.
How much lead time does a new phone line need?
Most lines are live in days. You send the call rules, the service list and calendar access. Lithium builds the voice and knowledge base from those, then hands you the number to test before a customer calls it.
Who answers when a pipe breaks at midnight?
The receptionist answers, then your rule decides what happens next. It takes the address and the problem, then transfers the caller to the person you name or books the first opening. The plumbing project in the card adds the text step: it tells an emergency from a routine job, sends the on-call technician the details and books the rest.
Which admin tasks can be automated separately?
Start with whatever your team retypes or re-sends after a call. Common builds are a request for a review, a text after the visit, a note in the CRM, a form read and filed, or a booking that lands on the calendar. Lithium prices each one on a free discovery call; most custom work takes one to two weeks.
Free action plan
Call the demo line, then build your own call plan
The demo line is live, so call it and hear the receptionist first. Then bring your call rules and the calls you miss, and a co-founder will map the answers, transfers and booking path on a short video call.
