Yeah, just walking into a supermarket and expecting to find a B2B connection is unlikely, but like you said, walking into a convention where your likely customers are is a great opportunity. Even coupling that with the other guys suggestion of just taping fliers everywhere outside the convention or dropping business cards on tables in the entryway lets you skip buying tickets to the convention but still get some boost from it. $300 will get you pretty damn far that way, enough to get a customer or two that you will hopefully be able to provide good enough first-class service that they'll help you from there.
