Build an Admin Panel

Hi freelancers! Right now we have a game account leveling service. We store the accounts in a text file. We want to offer our costumers the ability to store, and manage the game accounts in an online database. This admin panel will allow us to create costumer user accounts, and let costumers manage their accounts. the database is already created. I would like to have a admin panel for the account management. 1- go to [login to view URL] 2- Add a button like in [login to view URL] 3- Go to a Login page (including retrieval lost password) Admin login to an account manager, where they can add new users User login here, and go to the DB manager 4- Database Manager UI should be similar to [login to view URL] Listed data is exported from mysql where owner = username Here users can edit, add, and delete records to the database The main website is based in html5 and php. Please note what language and plataform you will be using. I will require at least one week of testing and penetration testing on our side before releasing the milestone. 100% milestone will be created once a proof of concept is accepted. NOTE: Very important, the main website is up and running, should remain intact, costumers depend on it. PLEASE DONT RUIN the main website to implement the changes from this project. NOTE: The Database scheme have a couple new fields, i dont have it here, will send it later. Any question dont hesitate and ask me in your bid. Happy bidding!
