FTP Restriction

I have a senario and i wonder how to do it ? i used NcFTPd and i dont think its applicable using that application or i didnt know how to configure it.

i want to have a user for FTP that user is only restricted to put and get from a certain directory and all sub-directories for that directory, the directory is not his home directory! and i want no restriction on any other user !!

NcFTPd only restricts to users home directory and affects other all users but root !! i dont want this !!

plz advise

thx in advance
