Perhaps reconsider the old business model for the NY (New Jersey?) show and the DC if you are up for that one?
That way you get exposure (hopefully positive write ups) with a one, or two, time expenditure.
I assume that you could drive to both events in order to keep costs down.
Adding detailed product info to the website would be a first priority (for me).
I have a tendency to think a lot about things often coming back to the/my original take that I have been trying to talk myself out of.
