Best online business ideas for 2011?

I am looking to start an online company this year. I have some of my own ideas, but I would love to hear the ideas of others as far as the best ways to make money online (legitimately). I am not talking about taking surveys all day... a real business. Some background information about myself... 26 year old married female with loads of ambition! I am currently employed, but looking to start my own company to become self employed. I have moderate knowledge about computers and SEO. I am by no means an expert, but I am willing to learn anything necessary to be successful! I am open to any suggestions... thanks!
