Hi Jean and welcome.
Setting up a standalone is really quite simple and clients from anywhere on your network should be perfectly capable of connecting.
I won't go into detail here on setting up as it's all detailed for you here in this forum and elsewhere. If you questions can't be answered by a quick search, there are many here who can help.
I'm sure your clients will enjoy such a thing and you also would enjoy setting up and delivering the simulator.
In simple terms "Go for it!"
Happy Gridding!
