SAMs Club carries a brand of freeze dried foods. Although as far as sampling, you would need to purchase a "30" day pail of meals.
As for just "meats", the smallest order I have found online is 2 - #10 cans. According to the manufacturer, 1 - # 10 can is 23 servings after reconstitution.
All you need to make your own is a large enough vacuum vessel that can be chilled to sub zero temperatures.
Look at this site for a free sample meal, it is up to them as to what you get. http://wisefoodstorage.com/try-a-sample
