ADMIN PANEL FOR PRICES COMPARISON WEB SITE - mySQL DATATABLE CODEIGNITER

This is a middle project that could become bigger. It is requested to build datatables with SERVER SIDE paging, SERVER SIDE sorting and SERVER SIDE identification of datatable correct answering page number after modification of existing fields or inserting of a new field. Therefore, it is required absolutely 3 main skills 1. strong query coding in mySQL 2. pregress strong knowledge on datatables development 3. codeIgniter MVC development The 40%-50% of the development is already done. Most of this development is to create the administration control panel. The end user development will be faced later on. Most of the development is almost a copy and past of already existing pages, just changing the mySQL tables to be modified and the column names of the reporting HTML tables. Some issue fixing and tuning on the past job must be done. I need to underline again that everything must be done on server side working on mySQL queries; I had 4 disputes with developers that made a messy on client side and they loss the disputes because of their bad outcomes. So please consider this job just if you are strong on datatables and mySQL query already. I attach a document showing some screenshots. The expecation is that the developer 1. develop on his server before uploading changes 2. test every new release before saying it is done 3. I will test the release on his server 4. when i will validate the release the developer will update it on my hosting space 5. IP agreement must be signed
