If You had to pick one Company to Run a Pop Under Campaign who would you pick?

[HeatTreat]

Hello,

I'm looking at using a company to run a small pop under campaign to generate some quick sales. If You had to pick one Company to run a Pop-Under Campaign to as safely generate some sales, which one would you pick?

Ive just had my mother pass away, and I was helping her with her business before she died. Her death has left me in a big bind financially and i need to generate some quick sales. I did some research a ways back, and i found a pop under campaigns could work well for my product, but had little feedback in regards to which ones where good. I compiled a short list from what little info i could gather on which companies might be good, and this is what I was thinking of picking from:

http://www.paypopup.com
http://valueclick.com
http://www.valueclickmedia.com
http://www.coolmediaplacement.com

Its a full page pop under I plan on running. I have a health product that many people need, and have a design (patent pending) that ensures a clear cut advantage over my competition. I will also be running a contest during the next 6 weeks that should somewhat help persuade others into buying the product.

If you guys have any insights on which company i should use, let me know PLEASE...

Ive also been told that if the company you use is legit, that purchase rates for every 1000 pop unders ranges from 0.1% to 1 %. If you offer a sample and or some kind of contest, you can expect a higher rate like 0.5% to $3%. Are these figures somewhat accurate? I know there are a lot of variables that come into play like your product, your competition, your price, your ad etc etc, but are those figures somewhat accurate? Thanks.

Thank you very much
