Andrew have a look around the game and events section and the after action section. a lot of fields run scenario based games as opposed to simple skirmishes theres even a group in ontario dedicated entirely to WW2 reeenactment. those threads might help give you ideas to improve your scenario
Milsim as a whole is hardly a new concept but at least this got the wheels spinning for you. if you can maybe refine the idea and get people interested in your scenario then maybe you can find a game host in your area whos already been doing this for a while to help set things up.
Just a thought take it for what its worth.
