Do you need just a payment gateway? Or do you need a payment processor who will actually process your payment (which a regular payment gateway won't do)? BTW, I requested to have you other thread deleted since we already have this one here.
ya... for thread deletation i asked ! there.... well... http://www.ccavenue.com i want sumthing like that which actualy process my payements
CCavenue or CCNow is probably some of your choices for 3rd party processing. A gateway won't really help you too much with a merchant account.
Diale will be the chepaer of the market ... but it is depending of your average ticket. you must understand that there are lot of hide fees everywhere and if you are not aware of them i could help you.
