Hi i will make you a web site that can make play list from youtube videos. The application will categorize all the videos you can create your own descriptions and play lists.
The application will be completely integrated into the site so they won't look like from you.
You users can also upload their own videos to your server. It can use amazon buckets hosting for this.
You provide domain, hosting, info and photos, graphics as needed. You can give a list of youtube urls to upload. I will make a terrific site for you.
