@khaled_ash Hi there, I feel I should add that the game is only accessible from an ea account/steam account on PC/Mac that has purchased the game, or via console but I have no experience on those platforms. This means that it may cause some issues with getting others to install it, however, if it were to be done on-site, it sounds doable so long as they use the device that it is pre-downloaded on.
In regards to the building itself, there is a bit of a learning curve to it which I'm sure youtube tip videos could help you with, but for a large number of users to meet the full potential to be able to make a real world plan, it can be incredibly tedious and time-consuming. I have personally taught absolute beginners and it's not something that everyone can pick up quickly.
I do however believe that if all of what has been said above is not offputting to you, it is an extremely useful tool to design real-world environments as I have done so personally to extreme accuracy.
For the items, you are looking for, and with the budget that I'm sure you are looking to not overspend on, my best suggestion would be to either just buy the base game and find custom content in the areas you are looking for (which are free, just may take a youtube video to explain installation) or getting a bundle pack when you buy the base game that will already give you a foundation of starting items.
If you are still interested in the game, I would be happy to give you more advice on the types of custom content/expansion packs that would be best depending on the type of options you are trying to provide.
