i'd do none of them...
Go to your favorite club - my fave nightclub specialises in twee indiepop and girlgroups. not rich man clubs, rich man clubs ae like boodles and are in pall mall.
Stay at home
won't meet anyone there.
Put an add in the newspaper selling a Ferrari
rich men won't buy second hand from a paper.
Hang out on a street corner
nah, rich gentlemen book their tarts.
i'd hang around hih class auction houses, buy coffee in banking districts and hang around those little 'grab-n-go' type supermarkets in rich areas during rush hour.
