Hey, I don't know how serious you are about what you're doing...(business license, business model, etc.) but the best merchant bank to go with if you are small is Card Services International. They deal with a lot of small businesses and give you the flexibility to look big instead of posting stupid paypal images or other fake "e-commerce wannabee" links on your site. Card services has serveral APIs through a company called Linkpoint and you will be able to handle payments like the big boys do.....if you know your stuff.
The (free) APIs are in C windows, C *nux, and Java. They also have wrappers that you can buy that are written in Perl, PHP, and ASP which will give you the flexibility you need on your site. If you are in a hurry, they also have a html-based commerce solution.
