More pages. A page per service is what local search actually ranks, so a five-service contractor gets more pages than a single-trade one.
Writing it for you. Most people would rather I wrote the copy than stare at a blank document for three weeks. That is a real cost and the quote says so.
Photos, a logo, a booking flow. Sourcing images, designing a brand, or wiring a real booking or quote system rather than a plain form.
Selling online is a different kind of build. Payments, stock and tax change the shape of the job, so it is quoted separately, still fixed.
