I need a user friendly webpage that allows authorized users to connect to a MySQL database via a browser and make entries (additions, modifications, deletions) to member & member_rating tables, if authorized to do so. Also, I need a screen (webpage) that allows authorized users to make entries (additions, modifocations, deletions) to the events table and ensure member id# exists; and, if they make a mistake to be able update the data so it is correct. How much would it cost for someone to develop a PHP/MYSQL webpage to do what I want?
