My two cents:
You'd be better off posting a general script , a.k.a. teaser, and asking for people with armor who would like to be in the film. Give them a little incentive... like a free BBQ when it's done, or something else. Just asking for armor won't help much. So beyond saying "I have a script" or "I know that" why not give some details on what you want to accomplish with the film and look to recruit "actors" not just armor. So give us a teaser of what you have in mind, and how you are going to help those of us with armor if we help you with your film project.
