Definitely get a rep. The P360 guys are money hungry and greedy and I love them for it.
Does your offer have a decent CPA? Dont bother if you're running a $5 CPA or an email submit crap campaign.. get a solid $35-$75 CPA into the pulse and you'll kick ass.
Now keep in mind, the top advertisers like on MSNBC and FOXNEWS, CNN etc have the top 5 positions locked. Theyre mostly by the same 5-10 rich bastards who bid so high it's nearly impossible to get in unless you closely monitor the time of day their ads turn on, and get your ads in during the hours theyre not there, which sucks because you go into knowing the only available hours for you are not converting for Mr. Rich Bastard or he'd be in that time slot.
So, your best bet is to find lower volume sites (e.g. MSN messenger) etc and start rolling there.
I know one bastard making about 100K a day on P360.. he runs 4 ads, 2 of the ads cover the costs of all 4 running, he makes his profits on the other 2. It works, but unless you have 5-10K right off the bat to really get into it, don't bother, P360 is really a high roller's hangout and like Gordon Gekko said, you can't piss in the weeds with the big dogs without cashola.
