Seriously, the best thing to do is learn about self traffic generation first and foremost. ( content is cheap now days 0 ultimatly you will need some content of your own, but that is semi expensive to produce to start out with .
Just start with a blog network, A
www.remotethumbs.com tgp network of your own, and some free sites you can get listed on linklist and such. submitt some of your own made gallerys ( not the FHG's )
and work on traffic development first.
WHATEVER YOU DO , DO NOT BUY SHIT TRAFFIC AS FEEDER TRAFFIC IT SUCKS! you are better off using that money to build and own more domains to do trades and link to and other SEO tricks. as was mentioned read YNOT, and green Guy and jim, and Netpond for their great newbie resourcses on how to start things cheap, they hacve some terrific advice offered out already, you will just need to read it and put it into practise .
once you get past that ( 6- 8 mos ) then there is more stuff but it starts to cost money then, so the KEY is build your own traffic first as cheap as possible .
