Holly, I don't know what clubs would be good in your area, but a good place to start is doing a search on AKC's site, and contacting those clubs to find out where and when they hold classes. Also they may have some individual members who do their own classes if the club itself doesn't do anything. Andrea might have some specific recommendations.
+1 on this. The way I finally found a conformation class locally was thru the AKC site and a local dog club that was listed on that site.
My other great resource for show stuff has been my pup, Liyah's breeder. I went to some dog shows with them recently and asked them to help pick out leads (they gave me pros & cons about the various types), etc. and then I just paid for everything. They have also spent some time going over the show basics and also got some of their show & breeder friends to help with some show training as well (so I'd have different perspectives). Oh, and they also found a handling clinic that I'll be attending this weekend. They'll be helping me with show entries & the classes to enter at the National as well, until I feel comfortable doing it on my own.
So maybe also check with your pup's breeder.
