Build a Website

I want to make a simple site similar to this: [login to view URL] The whole site will be caption challenges. I want to be able to post still pictures and short videos and let people make funny captions for them. I would like to have it EASY for me to post pictures/videos... I would like the site to look something like this wordpress theme: [login to view URL] I want the people who log in to be able to post with a FB login, Google+ login, or a simple login that they define on the page. I want the users to be able to vote with a "like" or "dislike" voting mechanism on each caption that the users submit. The ones that get the most likes will be at the top while the ones on the bottom will have the least likes or most dislikes. Some other things that I would like include: Archive of all posts with comments. Contact us page with an email address that comes to me. Ability for users to submit pictures and videos for me to review putting on site. Ability to post adds on page. Want to try to generate some revenue from site. Search bar for users to be able to search site for comments/pictures/videos. SEO optimized page. Thanks, Matthew Cobb
