How do I start my own internet business? (See Details)?

I like to make little crafts, like tiny clay models of cakes and such and make them into charms, or quilt, or make baby fabric books that are machine washable, etc. I'd really like to have my own website, where people can come and look at an item, put it in their basket, buy it, and I mail it to them - but I can't pay a lot for a web domain name. I have seen websites like etsy, but they charge you every time you post something. I'd rather pay a fee just to have the website, and then be able to control everything myself, but I'm not sure how to go about doing that. Any ideas? Thanks!
