Christmas Light Installers, Draw-Your-Roofline Satellite Instant Quote & Rehang Retention Engine
Homeowners trace their own roofline on a satellite photo and get 3 priced service tiers instantly, then pay a deposit to lock a real install date. A July rehang engine rebooks last season's customers at one click, which is where this industry's real money hides.
This blueprint is free. Copy the master prompt below, build it with your own time, and the only outlay is a few low-cost tool subscriptions. Use it inside your own business, or sell it to clients. The numbers further down are what you can charge, not what you pay.

Christmas light installs average $444. The storage customers are worth $9,000. Quote speed decides who gets both.
Read the articleWho you sell it to
Christmas light installation companies, plus the window cleaners, landscapers, pressure washers and gutter companies who run holiday lighting as their Q4 revenue. Find them by searching "christmas light installation [city]" in September and October, in local contractor Facebook groups, and by spotting who is already paying for holiday lighting ads (they have lead flow and a quoting bottleneck, the perfect combination). A good fit runs at least one crew, takes leads by phone or a dumb contact form, and currently quotes by driving out to the house or fiddling with Google Earth by hand, which takes days.
In this industry leads spike hard in October and November and the fastest quote wins, so a tool that answers in 5 minutes instead of 3 days is the whole sale.
If you sell it, here is the money picture:
The first tile is the value of your client's own jobs, which is the reason they will pay you. The other two tiles are what you charge them.
How it works
A homeowner lands on the installer's quote page from an ad or a yard sign QR code and types their address. The app pulls up a satellite photo of their actual house and they tap the corners of their roofline; the app draws the line, totals the linear feet live, and adds 10% slack for corners. They add extras (wreaths, garland, wrapped bushes, pathway stakes), answer one question about stories, and instantly see 3 priced tiers: install-only on their own lights, install plus January takedown, and the flagship full-service lease where the installer supplies commercial-grade LEDs, takes them down, stores them in a labeled bin and rebooks the customer every year.
They pay a deposit through Stripe to lock an install date drawn from the installer's real crew capacity calendar. The owner's admin side runs the whole season: quote review with a 2-story flag, a capacity calendar with one-tap weather rescheduling, a jobs pipeline from install photo through takedown to storage, and the July rehang engine that texts every past customer a one-click rebook offer using last year's layout. Two-story homes get a 25% labor multiplier and human review before install, so the satellite math never writes a check a ladder crew can't cash.
What to expect
Quoting speed is the measurable win: from days to about 5 minutes, during the 6-week window when every competitor is drowning. Industry lead costs run $9 to $27 (door hangers, yard signs, Google Ads) and over $40 on Thumbtack-style platforms in competitive suburbs, so converting the leads you already paid for matters more than buying more of them. The national average install is around $444 on light jobs, but professional residential tickets run $1,200 to $2,500, and full-service storage customers run $1,800 to $4,500 per season.
Push tier 3 hard: install-only customers rebook at 40-55%, install-plus-takedown at 55-70%, and storage-model customers at 75-90%, which turns a seasonal gig into a de facto subscription. Expect satellite tracing to land within about 10% on single-story homes; steep or multi-story rooflines need the built-in multiplier and owner review, be upfront with buyers about that. Twilio's A2P 10DLC registration takes days, start it before launch week.
And this is a seasonal product: sell it August through October, let the off-season retainer cover the quiet months, and the July rehang run is what proves the tool's worth in year 2.
