Fred Clarke at Sunset Valley Orchids does breed small hybrids. Go there and look at the Catasetinae listing. They aren't separated out by size so you'll need to look through the listing for the smaller ones.
He will post this year's new listings sometime in the future. If you add your name to his E-mail list you will get the new plant offerings before they go up on the Web site.
