I currently have a website that started off as a yousendit script, but I would like to create a new environment for my users that would work like dropbox.
Where they will have a certain amount of storage space and I also need you to develop the desktop app so the user's storage can be synchronized with 1 or several of his local machines. The desktop appliction should be compatible with Mac and PC and work with regular system folders
The site has 2 levels of users, free users and paying users, the only difference is the amount of storage they will have.
I would like to have the main dropbox features, like file synching, the referal program where the users get a little more space for each user they refer successfully or are if they are referred. It is very important too, for the users to be able to share certain files with other specific users.
Everything needs to work with language files as my site's main language is currently Spanish but it has various translations.
I will also need a comprehensive user admin, where I can see every user, the space they are using and their files. I should be able to upgrade them and downgrade them. Send them a collective email or a private message
If you have developed a similar site, please refer me to it.
I will provide all the pages already in XHTM/CSS format.
In general, I am looking for someone who is well familiarized with the service and is confident they are confident to recreate the features described above for a reasonable budget and timeframe.
IMPORTANT: Please be very specific in your proposal, as to the technologies you intend to use and also about the budget, it would be helpful if you break it in parts, so I can decide what features to choose and which to leave out. And your personal comments and suggestions.
