It's the next step I'm considering.
I've done 'booths' before when I was in the corporate world, and for the most part it is mainly people going from table to table trying to get a free pen, or a free pack of gum, whatever it is.
When you take into account the cost of a booth, the cost of the display (assuming you are trying to go 'professional'), and the cost of promo material, collateral, it could get expensive quite quickly.
I am thinking a better way to go about it is to actually put on a presentation at one of their breakout sessions.
Is anybody else doing this?
