Wordpress Plugin Customization (Tinypass)

Tinypass is a micropayments service that has a wordpress plugin which allows publishers to accept payments using Tinypass service. The Tinypass plugin offers an easy way for Wordpress sites to access the Tinypass API. Tinypass allows publishers to share revenue with writers through SplitPay ( [login to view URL] ). However, the Wordpress plugin doesn't currently support SplitPay. I need a programmer to customize the code in the Tinypass Wordpress plugin to do the following: 1. Get the post's author email through one of the author meta methods in Wordpress ( [login to view URL] ) 2. Add that author email to the Tinypass API call. This will require modifying the Tinypass plugin code so that it does this every time a payment is made. The SplitPay percent should be set to 50% on each payment. The only documentation I am aware of on this issue is on the Tinypass website ( [login to view URL] ). However, there is one blog post from a developer that added SplitPay to the Wordpress plugin but did it in a way that is not what I want. That blog post is here ( [login to view URL] ). Reading that post might help with this job, but to be clear I am NOT just looking for someone to implement the functionality described in that post. The functionality described in that post is mainly geared towards Pay Per Article, while I am interested in just setting a global function for handling of SplitPay.
