His flasking service won't be free if you're not sharing the plants/seed with others but his prices are very reasonable to do private flasking. He'll do a seed assay for you for a minimal charge and let you decide how many flasks you'd like.
Just for clarification, Troy's flasking service specializes in species, not seedlings. It is free only for species orchids with proper photo documentation. Having said that, I use this service for both species and proprietary flasking, and highly recommend it. Flasking is done in a thoroughly professional manner, plants are always healthy, and communication is excellent.
