Convince a couple of your friends to come to the first few weeklies to help bump start the event to success. If other people see that other people are playing in it, they will want to play too.
Pay Out Well. Our club takes a dollar from every entrant for the club account, but everything else gets paid out. We routinely have the winner of our monthly (singles) get $100 for first and we pay out a 1/3 of the field. The winners of our weekly dubs routinely get 40-50 bucks to split. When people see that there might be a nice pay day involved, even for 2nd place, they will come.
Post it to facebook. Post pictures of everyone who came to show others that people are coming (especially if you get a large group) and post a picture of the winners with their winnings. Post the prize earnings and publicly challenge people to see who can be the "king of Hoover" next week.
Do a club throw. If you have some extra plastic laying around (old club discs, tourney prizes, extra stock at home), have a club throw at some point, with CTP winning the prize.
And, like Bikinjack said, show up every week on time and be ready to have some fun.
