hi sir
i am senior developer with great experience using many advanced mvc frameworks such as laravel, yii framework, zend, codeignitor
my personal preference is laravel and yii2
i also have extremely talented skillful quick team of web developers with creative mentality that does not stop to your specifications and features but also can add more awesome ideas
we can program the site with elegant top edge well documented code and also add as bonus web services as a preparation for the mobile application that you sooner or later will launch it soon
then after you finalize this first phase of web development we can produce super elegant android app that will fit todays trends and will attract more users to the system, and if you are satisfied with our programming progress we can work on the app parallel to the web development because developing apps is little longer
by the way the cost of the app is reasonable and in my opinion in 2015 all goes for social apps now and you have great chance to get more users through app platform more than web platform
how do you plan to receive money from such project [ads system to allow users to advertise certain adds , web project to be apps platform to allow adding apps such as games]
or any other source of payments
all we need are the static pages you have or psds that will be converted to html responsive pages to imagine the project scale
regarding social sites we have some suggestions that we can share them together with a brainstorming
