I think that the mulch charge is a bit high, but this is going to need 12-16 cubic yards... So overall I think that the prices he's asking are acceptable.
Ok, I just looked at the bid again, do you mind telling me the size of the mulch area? I know we aren't in the same area, but I just got 2" of 3/4 Minus for my driveway, which is 5800 sf, and the total delivered cost was $1400. Granted, maybe Mulch is more expensive, but besides the Fire risk, maybe you will save a ton with 3/4 Minus?
If you look into that, ask if they have Tan. It looks incredible, but I was one week too late.
