What you describe sounds like a custom code job. It is probably not something you will find an off-the-shelf, ready-to-go script solution for. Whatever you end up must be integrated with your existing code, database, etc. You'll probably need to contract a developer. You can post requests in our Web Scripting Job Offers Forum.
