My guild always completes the raffle quilt at least 6 months before the show and arranges for it to be displayed at local quilt shops and other quilt shows/community events to sell tickets. Lots of exposure usually means more ticket sales. Guild members have motivation to help sell tickets as the profit from the show (including the raffle) pays for speakers at our meetings. Higher profits from the show = better national teachers. They also started making a smaller version of the raffle quilt and that is drawn from all the quilt show volunteers and awarded to a guild member. You could award a chance in the raffle for every 20 or 50 tickets sold (we sell for $1 each or 6 for $5).
