Website/Wordpress Development

I have a WordPress site that allows users/visitors to download FREE photos for their blogs, e-books, etc. These photos are taken by me, which I store on Amazon Cloud Servers.

I basically want to be able to upload a new photo in every new post I create and then users/visitors will click the free download button next to the photo of their choice (on the front end) so they can receive their photo.

While the photo is downloading, I also want users/visitors to be redirected to a separate "download page" that I can also modify on the back end, which includes a manual link, just in case the download doesn't work. This link will be unique to each photo I upload on each post.

Finally, there's a certain "look and feel" I want for the front end, when the user/visitor lands on a download page. For this, please email me so you can see what I'm looking for.

Thanks!
