Code Canyon Plugin Needed - Facebook page likes & ecommerce coupon codes

Hello Community

I am looking for a plugin in Code Canyon that can do the following:

  • Get people to like my Facebook page when people refer a friend to like my FBK page or when they like my page, they get a coupon code that they can redeem for services I offer.

Anyone please know a plugin that can do this function? Please let me know.

Regards
