Need some affiliate who provide food outlet coupons

Hi,

I have an Android App which has nearly 67,000 daily active users.It is only in India Currently i am using CPI networks to get app installs but now i am thinking to take this to next level. Our user base is mostly from younger age 17 - 27, most are students. So i want some affiliate network who provide vouchers and coupons for food outlets.

Please some holy sole guide me how to proceed. Any one here working with same kind of stuff. Even wants to work with me with CPS basses are welcome.

Thanks
