Jeff provided quality services for me. He is gruff over the telephone, but was very interested in negotiating the quality of the materials for my new porch screens. He entered a low bid to get the job, and we did sort of a dance about how much I should pay him as the job progressed (but the screening materials we ended up with were more work to install), but I think we came out mutually satisfied. After I paid him the enhanced fee, while he was still working, I called him with additional input about what I thought we'd agreed to. . .and he went back over the work before leaving the job to improve the fit and the joining work.
I'd definitely hire him again, and hope to do so.
