An existing website needs the following ;

[url removed, login to view]

The website provides a note sharing platfrom where users upload notes, set a price other users buy them.

Most of the following functionalities are partially done :

1- Paypal function :
Users should be able to withdraw money with a minimum of 10 dollars.
If they withdraw any amount less than 10 dollars they should be charged a fixed fee of [url removed, login to view] dollar.
Also for Deposit there has to be a limit of 5 dollars.

Right now users can only deposit.

2- A simple search function based on keywords .
Right now there is search function that only searches through note titles. I want this to be extended to keywords (for example when a user uploads a note with title "Algebra" in University of "Texas" in Course "X" I want other users to be able to type "X" and see a list of all notes that have keywords "X" in them.

3- Multi-file Upload, right now users can upload one file at a time, I want them to be able to add multiple files at the same time.

Also I might need to make some minor changes to the project description as we go through it.
If I want something else that is a major change you will be compensated.

Also my budget for this is $300.
