Changes to PHP site

Hi, I have a student classroom website done in php. where, both professor can upload files, pdfs and homeworks under different categories. the above was designed for 1 class. Now, the same professor has 3 classes and want the same function to be applied. So, what i need you to do is, create 3 class room folders in the above pre-custom built php website, and then apply the same upload and retrieve function to be put in each classroom. and at present, all the 3 classroom files are uploaded at one place, so i need a move ability, so that i can assign files to correct classroom. let me know if you have any questions, comments or have a better idea. thank you, need this done within 24hrs or less. ## 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.
