Hello Sir, your project is very easy to do and finish as I've been working with Drupal for years and made many sites and I can tell you that upgrading Drupal from 6 to 7 is very easy. And the Video and photo gallery can be done using a single module (lightbox2).
So I can start working on this project immediately, and hopefully I'll finish it in less than 5 days.
But you I don't have a rating on here, that's because I'm new to this site, but I assure you I will finish this job as cleanly and as fast as possible and you'll even want to hire me for future jobs.
