Could someone refer me to those who might help 25 to 30 octogenarians who still can shuffle around a dance floor?

My 89 year old mother belongs to a club with other very elderly people who stay young by being involved in their non-profit square dance club. They hold these get-togethers once a week and rent a building by the month with the membership fees paid at the door by all those who attend each week. My mother is the Treasurer and Secretary and says if they don't attract new members they won't be able to stay together and the club would fail. She and some others put their own money together and invested in some flyers to post at various places nearby and a Banner that can be seen from the street to be put on the side of the building. It wasn't until after they spent all their money that they realized that there was no one in their club who was capable of the physical requirements involved to climb a ladder and put up said Banner. She has been calling and asking the other members if they have kids or know anyone who might help them put up the banner. So far, they have come up with no one. I live in Tempe, AZ, but I told her I would look around on the internet for her since she doesn't have a computer. It appears that my mother is the one who is always responsible for getting things done. I want her to stay active because she is in pretty good health and I think that is due to her square dancing at least once a week. Other than that she gets little exercise. Sorry for being so long-winded. My hope was, that by contacting this agency, you might be able to put me in touch with some kind-hearted volunteers, perhaps living in Milwaukee or nearby so they would not have to travel far, who might take an hour to help put up the Banner for these, I think, 25 to 30 octogenarians who still can shuffle around a dance floor? :-) I really wasn't sure of the appropriate topic heading, so...
