custom wordpress template/theme.

Basically i want a theme where the users of my website can upload stuff with one click, like, comment and share other peoples stuff and follow people. The name of the website is [login to view URL] where people would open accounts/showcase to flaunt their skills or hobbies. People should be able create multiple showcases in one account. refernce theme ([login to view URL]). now i want grid style interface, a user page where a person can see stuff from the pages/showcases they have liked. Gif's should be playable. I want the homepage to show popular pages and option to login through facebook and google. People should be able to send other people messages. thata all. Give me a reasonable quote. Thanks You
