Developing Fieldplugin for SobiPro

Hi Guys! Thats what we need: Field Plugin for Sobipro! There will be a field plugin developed for the new catalog system Sobipro. The field plugin should be installed independently into SobiPro. The Field plugin would later create in a new catalog more a new entry form the following fields: - Upload a file to the server / download later (after payment) - Entry of the specific PayPal Apicode for each payment transaction (checkout via PayPal). The function of the plugin: When creating a new product, the members can upload their product on the server and make the input to the respective codes of their own PayPal Checkout for each system. Therefore, it is a multiple checkout system. The procedure: The customer places the product with all the necessary data to the catalog and insert the product and the Apicode for payment of the product. The user and visitors of the portal buys the product through a quick check-out and then passes on the side of each PayPal customer account. After the payment is made the payment has to be re-directed to our portal where it can be a download.
