It's worth asking at your local Surplus store if you can rent. For a recent production we rented some uniform, handcuffs and more. The guy was also willing to rent us prop guns. All of that was at a very reasonable rate, and rented for a whole week. You have to bring it back in good condition (so fake blood is out of the question) but it does give you access to a lot more variety than you can have if you buy everything.

It must be an obsession with Lego, but I really love your project Morley! It's flawlessly done and great fun to watch
