Buy tub / cylinder wall

Price requirements - specifications - number of 1000 sets of product packaging requirements - Tub and shower surroundI would like to find a vendor that makes FIBERGLASS surrounds for tub and shower. It is a 1 pc unit that incorporates the tub and shower walls (tile look). (The valve is not part of the surround, it would be a plumbing set with the valve, the tub fill spout and shower head as a set) I have no idea of ??cost for the surround, but we would need a 1000 of them. The approximate over all size is 60 "long x 32" front to back and 78 "tall.
