239437 web based uploader

I want to create a video uploader site. a user would login, then users can upload video to my servers and it will send the video out to multiple sites (for them) like youtube, yahoovideo, ridder and 20 more under their accounts for them using their user name and password. tubemogul does something similar but I want to add a few things. they are little so this is jest of it the rest will be similar but small stuff I will tell the one I accept to do the job. This should be simple for a programmer who knows what they are doing. thanks
