Searching for a client upload plugin for Wordpress

Hi,

I would like to set up a feature to allow clients to upload multiple image or document files to a client directory. The biz is a graphic design, I currently have a Wordpress site.

Ideally, upon placing a order, the client would be given a link to an upload page for uploads to a directory with their last name. They could return later for further uploads if necessary.

I thought there would be plenty of straightforward plugins to do this, but the more I research it, the more complicated it seems to become. Many plugins I've found are either outdated, allow only individual file uploads, require a page for each user (for client/admin file sharing), are simply too technical for me to set up, or place all uploads into one folder (which wouldn't work because they need to be segregated for each client).

In the future I can imagine a whole client area with a user login, then the upload page, but for now, the upload takes precedence.

If anyone has recommendations it would be greatly appreciated. Thanks very much.
