I have implemented a similar setup using vsftpd from the ports.  It works 
well for secure ftp when used with the filezilla client.  You can limit the 
ftp command in the vsftpd configuration file so users cannot get out of 
their home directories, which chroots them there.  You do need to add one 
thing to the accounts, which is to change their home directory in 
/etc/passwd adding an additional dot.  For instance if a users home 
directory is:
/home/user

You'd need to change it to:
/home/./user

vsftpd is well documented and relatively easy to get setup and running.
