php/jquery developer needed asap to get new auction site live

i am building a website which is 80% complete. We require someone to help with our payment API & gateway integration

The integration will be between WeBid (opensource php scripted auction template) & bitpay.com’s payment gateway and API. i do have the template scipts that need customizing from bitpay including the documentation

I am offering 1.5btc on completion  if you can do this, plus 10% share of profit from revenue relating to the site. for the first year payed on a monthly basis

I estimate that 10% will be around the $4000 mark (85 btc)
