Perhaps you might start by growing some of your Orchids outside where natural pollination will place. I always wind up with seed pods on my Orchids. Or get out the tooth pic and do some pollination yourself.
Regarding the sterile germination of Orchid seeds, one might start reading Joseph Arditti, he was instrumental in developing techniques to grow Orchids by sterile flasking and micro preparation. Google his name and you should get tons of stuff to read.
Come to think of it, one might want to include Knudson in your search.
starting with sterile flasking and branching out to meristem cloning.
