Payment option for Pro sites upgrade options.

I am an Indian user of almost ALL WPMU DEV Plugins.
PayPal and credit cards are not that famous here. People tend to leave BEST OFFERS as well if debit card and wallet type options are not provided to them. Please tell me how to add PayUmoney CCAvenue or Citrus etc. as payment gateway for my Indian users. Also if there is any plugin or something to do that do provide it else, please provide me with some custom code or do something as such for me please as my whole business depends just on Pro sites and I won't stand a chance unless this issue is resolved.
Shall be really grateful for any assistance provided. In case using any other plugin such as membership pro 2 or coursepress or marketpress shall let me add this - extra payment gateway in pro sites checkout in any way do tell me about that possibility as well. Ready to do any such thing!!! Thanks to all in advance...
