Instead, I like my interfaces to look similar to the image files I've attached. In addition to the plugin being created, I might need you on the hook for updates, and we can talk about that and work a deal out later about this as well. If this sounds up your alley then here is what I want you to do when you reply to this project to bid on it. The first thing I want you to do when you reply is to show me some of the types of interfaces you've built in the past (screenshots are sufficient). Then, the second thing is to give your estimation on how long it would take to get a beta version of this plugin working. The third thing is I want you to sell me on how good you are so I know you're the right person for the job. The simplest way to do this is to show me some of your prior WP work. If you have working WP plugins, either send me a couple for me to install and work with or give me temporary access to a WP install that has them available so I can test out the interface and functionality. One last thing: I expect a once a day email about the progress you're making if I do select you. If that's a deal killer for you, please don't bid on this project. Additionally, once the initial project is completed, I may consider any or all of the following potential features for future development: * Coupons for products so that people can issue coupons with expiration times or dates * Provide a mechanism for downloadable products to be delivered to buyers * Registration system that allows us to disable subscriber access if they cancel subscription (for future sales of the plugin) * Integration of affiliates into MadMimi (or other email A/R) * Integration of Business Partners into MadMimi (or other email A/R) * Integration of Buyers into MadMimi (or other email A/R) * Reports for Affiliate Commissions * Reports for Business Partners Commissions * Reports for Affiliate Sales (Listing or summary - may be used for contests or such) * Reports for Business Partners Sales (Listing) I have two plugins that utilize the PayPal Adaptive Payments system, but the one I'm currently using does not operate properly in a MultiSite environment - but works perfectly in a Single Site environment. I know what needs to be done to it, but it's been encrypted by it's creator so I cannot modify it. The second one is a plugin that is supposed to work in MultiSite, but the functions of the PayPal Adaptive Payments feature cannot be broken out of the plugin so it is unable to be used by my application. I can supply you with copies of both of these plugins to work with. Additionally, I have the code from PayPal's website if you do not have ready access to it. Once the plugin is completed, it will need to be submitted to PayPal for their approval process and I will need any modifications to allow it to pass PayPal's scrutiny. I can provide you with a sandbox website to work on if you do not have access to one; however, your location in the world may mean that your local servers would operate faster for you. I look forward to working with you.
