Many small household jobs only take an hour or so, and I charge $35 an hour and do not include materials. For jobs taking more than a day or so, I’m happy to give an approximate estimate based on the work involved.
I am more than happy to quote your job, regardless of size, free of charge.
At the same time I will advise you of any factors I’m aware of that may affect the final price. I also expect you to advise me if you want a job done in a specific manner. Otherwise I expect you to trust my integrity that I will do any job in the best way I know how. I don’t require prepayment, just pay at the end of the visit by cash or check. You can either supply the materials needed or I will supply them for you at cost.
