Weebly - The easiest website creation available. It is free to create a pretty basic site, but only costs like $60/year for the Pro version. With Pro you get up to 10 hosted sites. I have created 6 different sites with Weebly and it is awesome. I will PM you with links to some of the sites.

You can buy your domain from Weebly or go though any other domain provider. I use GoDaddy for all my domains, it is simple process to link your domain to your Weebly site.

Create a Google Merchant account and tie it into Weebly. Very simple and easy.

Google Sites = sucks, not very intuitive as to how to make stuff work. Stay away from Google Sites.
