14 cubic yards for 1500 sq ft. @ 3". I would charge your customer for another 2 or 3 cubic yards extra incase you run out. (16 or 17c/y) You Don't want to find your self asking your costumer for more money because you under estimated. Doesn't look good.

I work part-time for a decorative rock company,size of rock matters. 3/8 175sqft per ton
5/8 150 per ton
7/8 110 per ton all at a 2" depth. The depth used for most yards.
For a driveway, 3"-4" is best. I use a 1/4 minus product that is 96% lime. The material is marbleized limestone. I would bring in 20-22 tons, a full truck. We spread the rock, wet and roll it with a sod roller. Because of the inherent lime content, it sets up very smooth and hard, almost like concrete. I get $27 a ton for the rock and $35 a ton for the install.
