Please keep in mind that Kumoricon's sign policy forbids signs that are soliciting attendees, whether for money or services.
SIGNAGE AND SOLICITATION: No attendee of Kumoricon may wear or carry a sign offering paid services, whether for cash or other form of payment, offering free services, or soliciting behavior from other attendees. When in doubt, check your sign the way you would a prop weapon, with a Yojimbo or at the Operations Room, to make sure it is acceptable. Kumoricon staff and Yojimbo reserve the right to confiscate signs they deem inappropriate.
Hate to be the buzz-kill, but rules are in place for a reason.
