I agree PayPal is probably you're easiest option to setup for shipping and payments. You set up the type of delivery and shipping you will use with PayPal.com and then you incorporate your PayPal links into your site.

As far as your site goes, you can use Site Build It! like many here or you can do the "do it yourself" method and go to godaddy, websitepalace or whatever you like.

Do you have software to build your pages? If you don't buy SBI you're going to need some kind of editor unless you plan on learning how to code HTML from scratch.
