A Statistical Analysis Web Page for my new IOS App

I need a 2-page site constucting which consists of a login landing page and then a Statistical Analysis page for my IOS app which rates pubs and bars. The analysis will show the market of the pub/bar industry in whichever location of the world. It will need to have tabs that can be selected easily so that the user can view different information on the same table. I will also need a basic back-end which can be done using current software or site that you will have a better idea about than me. On the back-end, I will need to be able to create "groups" which will represent locations in the world as well as adding and removing pubs/bars from groups. I have a basic example I created to demonstrate what will be needed for this version of the website so that any bidders can get a better idea once they have made a bid. Please be aware that a large part of this webpage is to display statistics of the app users so you will need to have statistical analysis and display experience to be competent in this project. You will be required to work autonomously and be able to analyse my [login to view URL] information and pull the information from the app to be displayed on the site. Thanks and I look forward to receive your bids.
