I sent them a list that and of course, there is no guarantee that when they inspect the equipment, they will pay you the estimate on the list. This is understandable, but if the equipment is better than expected, I doubt they will pay more.
FWIW, of the multiple items I sent in, on one they found an issue that I wasn't aware of and on another they graded it higher than I did (and paid more).
