77107 Pop Up Killer app. with rights

I'm looking for PopUp killer windows applications to resell. It must be aleady built and fully working. I will need a full working demo upfront before i buy. I will also need full rights to this software, to resell, modify and issue reseller rights. This means i will need any source code. So you must be the full owner of this software. If your not, you could be sued by the owner ! Must be original programmed code. I will only spend a max of $200 per item, so don't bid above that.
