29" frame wanted

I am looking for a frame for a 29" road wheel I am building.

I’m mostly interested in a KH or Nimbus round crown frame with Magura mounts so I have the option of easily adding brakes later, but I will consider any frame with crown clearance for a 29x2.0 tire that will take an ISIS hub (42mm x 100mm) and either a 25.4 or 27.2 mm seat post. If 27.2 I could use seat post clamp as well.

I live in California, near San Diego.
