Someone once asked me "how much" it would cost to put some quilt blocks together to make a quilt. (they found the blocks while clearing out an estate). My answer...sight unseen and without any idea of how many blocks they had..I quoted "$100.oo minimum" and then I would quote the project once I saw the scope of the project.
I never heard back from them! (didn't surprise me either) Frankly, I made the mistake once of NOT quoting anything and ended up putting 25 hours of labor (and squaring the blocks!) and only reaped $60 for the privilege. Never again until I see what I am going to be working on!
