Bulid a Website for videos | Facebook-optimized

Hi there, I'm looking for a website, on which videos can be watched, BUT the viewer has to share the video on facebook before watching it. I will give you a few examples so you can know what I mean: [login to view URL] [login to view URL] [login to view URL] It should be like those pages, but it shoud look better...well-arranged, clear, user-friendly etc. And there should be two or three fields, where 728x90 banners can be integrated. The integration of facebook is really important, the user should only be able to watch the video after clicking "share" or "like it". And there needs to be a box for facebook comments below the videos. Also I should be able to add videos by myself, so you need to tell me how to do that after you have built the website. And you need to help me at searching a good domain name, it should be a german site so I need a .de domain. If you have any questions, feel free to ask me. Thanks. Best regards
