Hi joseph,
It?s very nice that you are planning to start online business but you have not specified what type of business you are going to start. But yes, I can suggest you to look for some of Affiliate Networking and other Internet marketing Niches. As you stated, you want to create website of your own, I would like to suggest you to check out some companies providing Turnkey Websites. Try http://www.layoz.com . It has unique affiliate links integration and all links are hidden with legal SEO rewrite rules from the source code and users will never have a feeling that the site is affiliated to 3rd party product. The XHTML/CSS code made with WEB 2.0 tables DIV markup making the site light and Search Engines friendly optimized. Hope this will help you.
Good luck!
