Are they species or hybrids? Do you just want enough seedlings to support your hobby, or are you going for commercial levels?
If you just want a single compot worth (about 25 seedlings) of a species breeding, I use Troy Meyers at the Meyers Conservancy. Just google a web site.
A single flasking of a species is free at Troy's. They will flask hybrids, but they charge for that.
I also use Troy Meyers. ( www.troymeyers.com) He has been doing my flasking for over 2 years.
He does Assay tests on the seed to see if there are embryos in the seed before flasking. The charges are reasonable.
