Type one line of work and a ZIP code. You get a contractor-cost ballpark in about fifteen seconds, with the labor hours, the rate, and the materials it used to get there. Nothing to sign up for.
This prices the job you described, and only that. It has to guess at everything you did not say: what condition the existing work is in, whether anything has to come out first, how awkward the access is. Every one of those guesses goes the simple way, because that is the only honest default when nobody has looked at the job.
A real scope closes those gaps. That is the difference between a number you use to sanity check yourself and a number you can put in front of a customer. Worximate takes the whole job, asks the questions this cannot ask, and gives you a document you can send.
