[WordPress] Add video support to portfolio custom post

Hello talented WordPress developers! I have a custom post type on my WordPress theme that displays a portfolio. Currently, it only supports an image which is assigned as a "Featured Image". This in turn is displayed in a lighbox (fancybox, actually) on the front end when clicked. I'd like to add the ability to display videos as well. I'm hoping for something like this (screenshot): [login to view URL] It should have a dropdown to select which video format and then a simple input of the video ID from YouTube, Vimeo, or Dailymotion. You don't have to bother with HTML5 video support. Just those 3 video hosting services. I'm willing to pay decently for a solid WordPress developer so please be 100% confident that you can complete this for me. Thanks in advance for your bids!
