SENDSPACE / YOURFILEHOST / DEPOSIT FILES - UPLOADING WEBSITE NEEDED

Take a look at [login to view URL] or [login to view URL] or [login to view URL] I basically need an option to upload with a regular uploader or a flash uploader like sendspace. User can register to manage their files is a must. Option for users to upgrade to a better account with more room and bandwidth. I've seen a couple of scripts like this, but I'm looking to see what else is out there. Another website that is similiar is [login to view URL] or yourfilehost.com. There must be a asp style progression bar. 0% - 100% along with the elapsed time/approx. time. i should be able to put ads on the download page, where the link is count down for 30 seconds. A DEMO is a must. I must see what kind of scripts or examples are out there before I can approve the winning bidder. I will most likely ask this person to help with future projects. I know how much most scripts cost out there, so please do not show me something I have already seen or free common scripts. Once again, DEMO is a MUST!
