Unity 3D survey and logins

Hello, i need someone to do a Unity 3D online server where i can store certain information about users. They will be requiered to login in order to complete, and must store their login information as well on database. Both email and facebook login are allowed. Username must be stored in game. A survey will also be present which must added from that same server. I already have some files available, your task would be to transform it or start if from scratch if you believe scripts aren't too good. Must be done in 2 weeks.
