What schooling do I need to become a home based travel agent in Arizona?

I have compartment syndrome and it has limited my mobility, it will be a while until I'm recovered. For this reason I started to think of home based jobs and I thought of becoming a virtual travel agent. I can dedicated 40 hours a week with no problem and will happily do more if needed. I think it will be a good field because I love travel and I have good customer service skills.

I live in Arizona...might move to Colorado but for now I'm worried about Arizona. I could find what I needed exactly on Google. eHow had something but I don't think it was correct. I didn't think that travel agents needed to have a degree, I did think that a certification would be needed though.

In order to become an independent travel agent (beneath a host agency) what do I need? A state business license and probably a tax ID number..I think. Can I get a certification? Do I *NEED* a degree? I can't afford to get a degree but I can afford a certification, even if one is not required I will probably get a certification just to help get me started. Please help(:

Thank you
