Create a Wordpress Template

I'm looking to use this template as a framework (([login to view URL] ). I'm creating a website to promote my photography by holding weekly contests for the models I work with. I'd like to pictures along the bottom to be clickable (or a button underneath be clickable) so people can vote for an image. I'd love to be able to use a plug-in like this ([login to view URL] ) so users wouldn't have to log into the site to vote AND sharing would be more automatic -- if it can integrate Facebook, Twitter, and Instagram to be able to vote, that would be even better. I need the site to be easy enough to set the number of models each week (this week might be 10, next week might be 5, etc.). I'd also like an easy way to archive each contest so people can go back through and see them after they're complete. Finally, I'd love for the full screen background image to change based on who is in the lead. I'd like that picture to be different than the picture people are voting on -- i.e. if my photography theme is "water" that week, each model will have an image where they're interacting with water. But I'd like the fullscreen image to be more of a generic image that may not have to do with the photography theme of that week. Thanks!!
