i need a software like facebook ads, where i can sell advertising space in our site , cpc or cpm , and user can pay direct per paypal or creditcard. any idea where i can find this ?
Do you mean something like OpenX (www.openx.org) ? You can google for other ads serving scripts as well.
no, in openX i can submit banners, i need something like in facebook on the right side, where user can sumbit a image, a 10 word text, can define how much they want pay per cpx/cpm, can do the payment online.
