Design business

Ok, please don't laugh, but I have had this dream of starting my own Web Design business. I don't have much actual experience, but I have taken a TON of classes on HTML, CSS, and Web Design. I feel I am ready to start, but I don't know how or where. I have my own domain, etc, but I don't know what to do with it.
Is there anyone who can tell me / show me what I need to do from here?

Thanks SO much!
