You have chosen to sponsor your bid up to a maximum amount of .
We currently have a PHP cart that exceptes Credit Cards using Authorize.NET and we need to integrate:
a. Paypal Express Checkout
b. Amazon Payment services
I need an experienced, proven coder to write the code that will execute the purchase through these api's then deliver us the necessary info (name, billing address, shipping address, etc) so that we can grab the data and place in our database.
You must have a cart example you have done for reference. I will not award this job without any working 'live' samples in paypal express.
