PayPal REST API

I’m looking for some help using PayPal REST API. I would like to be able to:

1. Authenticate using OAuth 2.0

2. Create a payment using direct credit card payments

3. Look up a sale

4. Refund a sale

5. Look up a refund

The documentation and resource references can be found here: [url removed, login to view]

The deliverable will be a well-structured C# windows application (Visual Studio 2013) that uses HttpClient to perform the above functionality with PayPal sandbox credentials. The JSON input and results will need to be translated (serialized and deserialized) to C# classes. Once I’ve tested sample app functionality with my own live credentials and code is reviewed for cleanliness and efficiency with satisfaction, the project will be complete.

If you are interested in this project, please indicate your experience with PayPal REST API, HttpClient, when you can get started, and expected time to complete.

I would like to get started on this as soon as possible, so please provide your most competitive bid.

Does it sound logical to you to have your paypal API credentials residing in a customer facing application? I would build a server that would process paypal requests on behalf of your customers.
