The swag idea has some potential. Though there isn't much market for people paying to get startup swag, I feel that many startups would love to outsource the actual shipping out of their swag.
True, the market isn't huge, but for good quality content some would be willing to pay. We have thought about this a good deal and creating merchandise that stands out, and offering good fulfillment services is an area that hasn't been fully tapped thus far.
