ok,how about this,get some expensive looking flyers and cards printed,spend a day dropping them at top hotels in the area, eg Palace Meredian, Brittania, Mal Maisson,Lowrys in Manchester for instance, i work near to the palace and the people to see are the porters,they deal directly with the guests, offer to bung them say a score £20 for every punter they get you and watch the bookings roll in, when the games were on taxis made a fortune from the hotels,eg £60-00 to £70-00 to the airport, all the mini-buses that get work from the palace bung the porters, old saying, money talks bull**** walks :D
best of luck anyway
P.S wanna buy a LS400 :D :D :D
