Develope Payment gateway for Miva 5

The project is to develope payment gateway module for Miva 5. You have to be a Miva script guru to do this project. The payment gateway is Protx in the UK. I am using Protx Form with Miva 5 at the moment. I need a Protx Direct module to be developed so I can get customers finish purchase without leaving my website. If you have done any similar developement under PHP or Perl before it should be quite simple. Miva script is easy to understand and write. You can see more details of Miva script here: [login to view URL] I will ask for technical support for at least 3 months to tackle any issues, also need the source code in case any change in Protx side in the future.
