Online Platform with Mobile Apps

To Build: 1) Website with Yii framework, with mobile version. 2) IOS and Android apps for the website. 3) To set up concurrent server, 2 servers to be deployed, with settable secheduled backups. 4) We are looking for existing website with mobile version template that you can use of to build the website. General Features: 1) Safe, secure and stable, no lagging for website and no lagging apps. 2) Fast and lightweight script where it can handle 200-300 visitors with one dedicated server. Features: 1) Able to scrape data from another existing online platform, and store them systematically, and able to compare with data in our database with our own rules for logic. 2) Able to setup a spam filter for our online contact form which gets delivered via email, where enquiries that cannot passed through our filter will have to be approved or disapproved by us manually. 3) Able to setup traffic analysis which not only show the analysis of the whole website, but also let us generate PDF report for individual companies on our website, monthly, where we can manually configure which page or data belongs to them, or even if they display Ads on our website we can add them to their monthly report. (And of course, it shouldn't be too poorly code that it cant even recognised google bot or other bots and add them to the traffic record.) 4) Able to easily spin up sub websites such as [login to view URL], [login to view URL] for individual companies. Please reply with the questions below when messaging me. 1) For concurrent server, what DNS load balancing will you suggest, as there will be 2 or 3 server at max? For concurrent servers setup, what will you setup for me? Parent-child? or? 2) Are you capable to build the website with NoSQL such as mongoDB or so which claims to be highly efficient for high traffic websites? 3) What existing framework will you use for scraping data, spam filter, and traffic analysis?
