The model below is the same one we price from. It is an estimate, not an offer — scope changes the number, and the quote we send will say what changed.
The calculation runs in your browser. Nothing is sent anywhere until you submit the quote request.
Scoping is free and takes one call. If the data cannot support a defensible claim, we will say so before an invoice exists.
