I do about 20K a month in media buys but not in the IM niche. You will get your wallet cleaned out in the IM niche big time. javascript:replaceText('%20;D',%20document.forms.p ostmodify.message);
You need to do this in the shopping cat. and diet areas.
Other then that you need to test like a FREAK>.
You will make $$ or loose a lot of $$ all based on just a fraction of a %.
You need to have the best creative that you can get and test.
Also you need to have your own Adserver running.
Most of the players will want a 5k IO to get started.
Thanks
