I understand why Starling posted her message. I also agree that leopard geckos would be an awesome teaching tool; congratulations for receiving the grant!
What I don't understand is why you need such expensive morphs when you can do the same with much, much less expensive morphs. I see that your grant was $2500, so you won't be buying 8 high end 'hybinos' and 10-15 HCTs. Are they for the project as well? What will happen to the offspring of the geckos; who will get the profits, or will the offspring go to the students/yourself? This is why you're likely to get static about this message from this forum. People who come here LOVE these geckos and don't like to see people come in and ask how to make a quick buck, often to the detriment of the animals.
To answer your question on where to find these animals, just go to the forum sponsors up top and the breeders list on the front page of Kingsnake.com. You're bound to find what you're looking for. Hopefully you've been reading the forums for a while, becuase you can learn a lot from others here about leopard gecko genetics that you can pass on to your students.
Something else to try, and someone did it here earlier this year (Jeff Medley, I think), is contact some breeders about donations of their geckos. You may be able to keep down your costs that way.
Please come back on here later on and let us know how it goes with the project, I'm sure someone will be real interested.
