If you have a website I think that it would be a good idea for you to look into Google's Adsense program which is a program that lets you add ads to your site and you earn money when visitors to your site click on the ads!
You can find out more about the program by going to The Adsense Consultant's Blog at:

You should also look into trying to get direct advertisers as well - a good place to start would be with local business and then you could branch out.
And of course one of the best ways is to continue your networking both online and off - I hope you have some business cards ready to hand out.....
