The LFS's should buy them. I did have a conversation with DNA, and they would buy them. All that they require is an IRS form which states you sold them the clowns.
Make sure you read that article. I would guess you won't be ready for the 1st batch of eggs. You would have to have rotifer cultures in place and a larval tank. They may not do their thing for awhile. Might be best to let them start spawning knowing you won't be ready. If you just get your equipment together and just wait, you could probably be ready for their 3rd or 4th spawn. Get your culture containers, air pumps, etc.... With you in Dallas, I could get you a starter culture of rotifers. Go through the article. It will tell you what all you'll need.
