You know what's good for raising money? Raffles.
Yes, employ a gentleman jewel thief to rob the audience's homes whilst they are at your meeting.
Also, a batchelor auction. A lot of the people in your target demographic are elderly women, perhaps widowed. They have a hard time cleaning the gutters and doing the garden at home.
Auction off a young man to be a slave for the day. A fifty year old will do. Get him stripped to the waist and baby oiled-up, fireman calendar style, perhaps holding pruning shears in a suggestive pose, put him on stage and watch the old biddy bids fly.
