It's probably time for the company to spend a small amount of money on an "investor awareness" program. Since no big name firm/analyst will provide coverage on the company at this time, bite the bullet and enlist a firm like Taglich to provide the analysis/coverage. There are a number of other firms that will provide similar for as little as a couple thousand dollars for a one time report and publicity, to maybe $20k for one year coverage from Taglich.
I think that this is part of the problem as you have similarly pointed out...for the stock to go up, people have to be buying it and there needs to be more than one or two trades a day.
Doing this would be good not only to get more investors aware, but with a higher share price the company would have more/better opportunities for securing financing going forward whether that be through equity or debt.
