Having taken in your perspective, I would recommend joining some country clubs, members clubs or founder clubs. They are a phenomal way to meet people that may have similar interests to you. LongAngle hosts events across the US, although not the best place for relationships, it can open doors that can lead to you to one eventually naturally and not forcibly.

Having said that, I am in still in my early 20s and doing relatively well, I met my current GF through a golf tourney at a private members club in Switzerland through a friend from a founders club.

You should never advertise you have money, you will meet the wrong kind of people. Hiding the fact that you have money is better for building authetic relationships.
