Let Way Cool Web Design get the ball rolling for your online venture. Using Drupal, Ubercart and PayPal Pro you get a full-fledged shopping experience - the user does NOT leave your site to make purchases.
For a more budget-conscious approach you could consider the free standard PayPal account and use the PayPal cart/buttons where the client leaves your site each time the cart is updated. Either way we have what you need to get your site ready for paying customers.
Absolutely awesome job John!!! They're going to love all of these [logo designs]. The only problem I see is that they can only pick one of them!L. H., New Media Consultant
