Build a PayPal Service that can send payments between users


I need a java service built in that uses one of the Paypal API's to facilitate money transfers between users of the system. The job needs to be accepted within 30 minutes of award and must be completed within 5 days of award acceptance. Funds will be deposited into Freelancer escrow and released once the code passes peer review and all testing. The code must adhere to the Paypal API authentication flow, must handle error handling built in, must be well-commented and shall have the following method signature:

payViaPaypal(String senderEmailAddress, String receiverEmailAddress, Double sendAmount, String apiKey)

This service method will make a call to the paypal API to authenticate and to handle the money transfer between the sender and the receiver.

Note: The project must be completed 6 days after the project is awarded. To ensure that the project is completed within the alotted time, for each day that the code is not complete past the 6 day mark, the award amount will be reduced by $50. However to encourage the developer to finish sooner, for each day that the code is complete prior to the 6 day mark, the award will be increased by $50.
