We feel that it would be much better to build your website from scratch rather than using any open source software as the website would require a lot of customization to match your exact requirements. We've reviewed your requirements thoroughly and everything seems quite feasible. We propose to build your Social Networking website using Custom PHP with an MVC framework like CodeIgniter, which will provide more security and scalability for future. We will provide a Custom-built CMS, which will be linked with a MySQL 5.x database.
All three Major components - 1. a landing page with content for general users, 2. Profile creation, dashboard, Chat system, rating & review system, comment, share, post, picture and video upload etc. features 3. a user friendly Administrative Panel to edit, update and manage all the contents and user accounts of the site with ease. We have reviewed the attached document and everything is completely feasible. The coding will be fully optimized, so that the pages load much faster.
We would use latest frontend development technologies like HTML5, Bootsrap CSS, JQuery, AJAX etc. to craft a sleek User Interface with fluid navigation system to provide maximum user experience. The Website will be responsive (Mobile friendly) at every pixel.
After project completion we would provide you 6 months of Free Support.
