PayPal PHP Integration

Ok, this is the solution I want implemented in 3 places: 1. Validate the post back to our site using this process: [login to view URL] There are sample php codes in paypal and online 2. If successful, set the session that I need to show that user got upgrade, etc. 3. For testing, I would like a paypal sandbox set up so that I can see it working. 3. Then, I would like it done with a video or screenshots showing that it is working with the live site (as I don't have 2 paypal accounts I can use). Thanks. Please let me know final pricing and time to do so I can select. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
