PHP Script for PayPal Permissions

Need a PHP Script that will use PayPal’s Permissions API to request a token from PayPal and then send the user to PayPal with that token. Then need another page that will receive the response which will contain a secret and the token. This job should cost less than $50. See [login to view URL] Basically exactly what is done in the three files : Permissions/[login to view URL], Permissions/[login to view URL], and Permissions/RequestPermissionsResponse.php. What I need different is I only need this one call to work and I need it to be done from one class. You will see the many dependant libraries in the included SDK. This API call is extremely simple using CURL all of this extra stuff is unnecessary. I need this done in one class with no dependant libraries. Be sure to also display errors as well.
