Accuate Miniatures used to make a series of 1:100 scale injected plastic helos, including a SH-60B Seahawk (that is the helo you want for your application). They also made a UH-1 Huey, a AH-64 Apache, and a UH-60 Blackhawk.
I believe that the product line closed when AM had one of their business downturn/consolidations. You may be able to locate one on eBay or at a model swap meet.
