Help the gallery submitters out.

I'm about to get hardcore into gallery submission, and am in dire need of your help.

I just need as many facts, tips, opinions, realities, and tricks to the trade as I can get. My main question is what kind of content should I use to build teen galleries? Should I purchase it, or would it be best to start out using free content? Could I just take a sponser gallery page such as epiccash, and submit those without using any of my bandwidth? And where should I get this free content? What sponser should I go with as well?

And another thing that I wasn't sure of, is after I build these galleries, and host them on my site www.teenlinker.com for submission, could the mainpage www.teenlinker.com be a means of income as a free site? I'm just wondering how the foundation of this project I'm starting should start out to get a smooth ending.

I realize that I may be in left feild with a few of the things I have said. Thanks in advance.
