I did ask for $850 up front and the rest upon the completion of the job. Thanks for the thumbs up babe!!I don't see any glaring errors. You added a markup on materials and budgeted in profit, which "newbies" often don't account for, so two thumbs up on that. I suggest that you get a deposit of 1/2 the total or your materials cost before even thinking about scheduling the job. Once it's installed the property owner owns the materials, whether you get paid or not.
