Sparky:
That's a tough call, to provide info, or not. Over the years, I lost many jobs that were done with info I provided. Be it a 'spec', or a drawing, or a written estimate.
I feel it boils down to you (or me) making a judgement call as to how much of our info to provide to a client.
It's a tough call! Having previous dealings with a client would be one measure to use, but with resi HO's that we never dealt with....good luck.
BTW, before I put the EC key in the door, I spent probably 100+ hours working on a large comm job (TV studio expansion); gave the papers to the EC who took my equip & clients. He put 50+ hrs into it, & would up loosing it for $3k on 200k+ job, without even the courtesy of a phone call!
Flip a coin, make a decission & live with it, that's all I can say. Good Luck!
