Restricting users using one port

I have ssh running on port 22 and (say) port 33333. Port 22 is restricted at
layer 3 so not much can get to it. Port 33333 is open to the world.

I only want to allow one user to authenticated using port 33333, but
all users to authenticate using port 22.

Is there any way to do this without running 2 sshd processes?
