payment gateway return code fixing

Dear service provider My site is wordpress based with jigoshop as shopping cart. We have put an alternate payment gateway (ccavenue) which need some code fixing. The service provider need to fix up the code [login to view URL] which comes after the payment (through payment gateway )is complete. It should give necessary inputs to wordpress shopping card (like order completion, making the post featured...etc). Its small project with budget of 40 USD since functional codes(from like of paypal, mneybookers etc) are already there. it just needs to be modified for the newer payment gateway (ccavenue). The service provider we are looking for should be comfortable with payment gateway and most importantly should be responsive. best of luck bidding.
