If you round up to 12 yards, 162 bags X $ 2.25 = 364.50 + tax.
In bulk it would be $ 408 for 12 yards.
With bags you or one of your guys could pre stage the bags and then everyone else (or you) could just follow behind and spread them.
With bulk the quality may be better and the amount easier to get plus you can get it delivered.
It's not the equipment that makes a professional, it's the operator.
