Use proFTPd. I believe the default config only allows access to a
user's home directories through ftp, but make sure.

Then set their login shell to /bin/passwd or /bin/false or something
similar to prevent them from being able to actually log into the box.

And make sure you have no other methods of logging into the machine
running that won't use /etc/passwd login shell settings..
