internet home based business idea

Home-based businesses?
What are some good ideas for a home-based or internet-based business that has low start-up costs? I’d like to start someting part-time, as I work full-time, and see if I can grow it into something bigger. Any thoughts?
Could you incorporate the activities you enjoy about your full-time work? Putting them to use in some form on the internet should not be that expensive. People do that all the time by making a website which leads to their site or by networking with business partners perhaps with people they work with who are also interested in doing the same thing you are. You see how the people above have worked to find you?? Well, that is a tactic that you might also try. Use your avatar as links to your business page too! It still costs you nothing!! Careful!
