Php codeignitor tasks for an existing project

1) The admin should be able to create and update blog articles which will appear on the blog page of the website. 2)  The admin should be able to create a package with min price , max price and daily returns % (This is already done) 3) The user who sign in from the frontend should be able to purchase plan from plan tab. While purchasing plan, the user should enter an amount in between min and max price of package created by the admin. Once the user enters the amount and clicks "BUY NOW" the entered amount should get deducted from the cash wallet and transaction has to be created. Please note : The existing website is already working and deducting fixed package cost from cash wallet. At present, the system already adds, the daily returns amount to Daily Profits wallet every 24 hours. This feature should not be disturbed and working after package feature has been modified. 4) The user should be able to place "AD FUNDS REQUEST" from dashboard and the admin should receive the list of requests. Once admin manually processes the request, he will mark the request as complete. (The database for this is already there ) 5) Other small bug fixes with registration Please get in touch, if you need further clarifications or have any doubts. I would be glad to help with the solutions as well. Need the work to be completed as soon as possible.
