My advice would be to move to a hosting provider that can scale easily with the success of your site. I like linode. If your site isn't generating much traffic, $23 should cover your hosting expenses ($20 for a single node). As your traffic scales up, add additional nodes.

I'm not really willing to sign up on your site, and almost nothing is viewable without an account, so that's going to be it as far as advice I can offer. Good luck!
