Im not familiar with many stone types. I only use a few colors in small quantities if customers inquire about it. I have a large job for march 06 comming up that the customer is now going from mulch to requesting BLACK stone around his huge pool. The pool is an L shape and im looking to cover an area after trees are put in about 200ft long around the pool and 6-12ft in depth from the cement to the fence. Ive seen black onyx rock, river rocks that are flatter pebble like, ive found a couple like this ONLY in suppliers FAR away in other states and for $50~ a bag, id need about 2-3 tons worth of rock. Bags would cost around 30,000$ just in rock! The customer isnt too concerned about its price but 30k will knock his socks off. Any suggestions on what types of rock i should search for and going prices per yard or ton, truckload would help, thanks!
