I am not a travel agent, but signed up for a sabre system. It works GREAT! It is an actual travel agent system. Check out

Once it is installed, the log in is

It costs me $47.98 per month. The system runs on my laptop (so I can use it on the road). Well worth the $47.98 per month. You will need to learn basic travel agency booking codes (like a real travel agent), but their web site has lots of good info on how to do this.
