First of all, a small job may not be profitable but if you are accomadating and reasonable it may lead to more work and referals. I always explain the minimum on the phone and suggest to them they might want to come up with a little more work to make it more cost effective for them, say some new lights or a fan. Almost everyone has a place they've always wanted a receptacle, now is the time. Some of us have slower weeks where these jobs make nice fill ins.
