Freelance Designer looking for assistance

Hello everyone,
I joined these forums a few days ago and this is my first post here. The reason I am posting is because I am interested in doing freelance design work but I am a bit in the dark as to pricing guidelines for such work. One site I have found for such guidelines is http://www.freelancers.com/webaffil/priceguide.html, but I’m still not sure if these are current or even proper.

If anyone reading has any tips or web sites with current guidelines they can post it would be greatly appreciated.

Thank you.
