Have you and the guys ever thought of using Youtube and other forums to advertise some of your already existing product? Many of your battle markers and tokens would be gobbled up by Flames of War and Bolt Action players. I think a demo of HBG minis being used for Memoir '44 battles would also be a boon to your sales. Lastly there are players who play other games that may become interested in Global War when they see what they might be missing out on.
I listen to several podcasts in different genres of war gaming. They frequently point their listeners to small companies that make accessories or custom minis simply because they love the product. Often, (like HBG) the smaller companies they advertise or mention make a less expensive and superior product to the OOB pieces and accessories.
I would love to find someone who would do this for us and work out pay in trade or work out something where we do not spend too much money. We are doing some videos for 1936 and plan on doing more but I agree we need to do a better job showing our product. If you know someone interested in doing this have them PM me.
