PHP / CRE loaded expert needed for coupon customization

I have a CRE loaded store which needs some customization of the coupon module. It needs to be done really fast, and really well. We have a heavily modified CRE store, with a custom affiliates system, with whole separate sites for different affiliates, on different domains, all drawing from the same product database. The coupon modifications are to link the coupons from one system to another, and set up popup messages, emails, and expiry times to help prompt the customers to use their coupons. This is just one small part of an ongoing, and pretty large scale web development project, so I would like to use it as a means of finding another developer for our team. I need only extremely experienced CRE / PHP developers to apply. I can't afford for any time for someone to understand the basic CRE framework, since it will already take some time to understand the customizations. No payment will be made in advance. You will need to spend at least one day working, communicating with myself and another developer, and showing me some results. Must be available on skype during business hours NY, USA time. Thanks!
