I also do the graphic designs for Pithy Productions , a web production company that my mom began in 1999. We specialize in eCommerce sites using osCommerce and CRE 6.2...woot.
I'm also the customer service department for oscommerceguides.com soon to be oscommerce-resources.com, so don't be an a-hole if you have issues with your ebook, or else I'll send you a very firmly toned email.
