Hello, Do you guys know any company who offers almost same solution' as 2checkout except for Paysystems ?

Have you checked out http://www.payquake.com/

I don't know how they are and if they are still around..lol but propay looked promising a couple years ago.

you can try ikobo.com
they won't charge you setup fee and monthly fee.
they accept 170 countires payment and charge you very low transaction fee.
