Hi there. I have to say, I'm quite the fan of carnivorous plants myself! I've always found that you'll do much better if you mail order rather than try to find a variety of these plants in local nurseries. Terrarium and vivarium suppliers are usually a really good source.
Black Jungle Terrarium Supply is a company I've used many times - check out this link to a special they have going right now: http://www.blackjungle.com/Merchant2/me ... ry_Code=CP

You might also want to check out the International Carnivorous Plant Society. As a member, you get a great newsletter and you have access to seed banks.

Have fun!
