We are a small printer looking for a private site that we could invite our customers to. Here we would have a special page that only that customer could see. That page would have a place for file uploads, PDF proofing, and a place that the customer and printer (us) could leave instructions for one another for changes and such. I'm looking for mostly for a canned solution for this project, as i don't want to spend too much, just in case our customers or staff hate it. I figure we could use "Simple Invites" to do the inviting, some type of form plugin to do the text fields, and as for the FTP portion, we have a solution now that we could incorporate in. Please offer suggestions as how we could do this. If you are a CB freelancer and are interested, drop me a note.

here is a mock-up of what it might look like
