for 4000 yards, you should be able to find people within the state of NJ. I would think hauling from out of state would be cost prohibitive. The most yards locally delivered is 80, and typically interstate, they cut the amount down to 70 yard loads.
There's banfe, frey brothers, zeager bros., county conservation, south jersey agricultural products, natures choice, to name a few in the S. Jersey region. I realize you may be in N. Jersey, but I would think it would be a similar case further North.
We do about 10,000 yards these days, and utilize a local company who offers a very competitive price.
