Try to play with as much of the technology as you can. Make a great web page advertising your work and start to find people you can create web pages for. Right now, the best market for new companies is regional. Develop a site for your region. Join your local Chamber of Commerce and get members to use your services.
Word of mouth is usually the best way to develop a customer base.
Make sure you have a place to put these lovely pages after they are done. There are a number of Web Service Providers who specialize in providing web space to small web publishers. You might find your local service provider is even willing to give you some space for a good price. You can either resell the space or refer your clients to the provider and get a finder's fee. There is a lot of competition out there.
