Curved radius window parts

I am in need of curved radius window parts specifically frames and sash components that have a convex curvature and a radius top. We would provide blocks of wood to cut and route the parts out of. The wood spieces we would provide is sapele. It would just be the top rail part of the sash. The stiles we would manufacture and of course assemble in house. We often make curved windows in house, but this one is unique in that it is 1) curved and 2) has a radius top. We would be open to someone providing the programming for our SCM 5 axis machines, or sending you wood blocks to make the parts out of. Attached is a photo of the windows.
