Hiding WP panel with Pro Sites.

So I am trying to customize my WP menu for Pro Site users so that they only see a couple of tabs – preferably the Appointments+ Tab and the Users tab (for now – I may add more later). Is there a way to limit the tabs that are seen by Pro Site users? Since this is run on WPMS and my website, http://www.booklyonline.com, is on the network I find that if I limit anything it will also limit what I see on my dashboard – and I need to see everything.

Would I be better off using a domain that is not on the MS network to create as the platform where people sign up for the service? Not sure if that is even possible. I hope that this question makes sense, if not please let me know and I can explain further.
