Old men soccer team?

Hello, this is a little silly but, my dad’s birthday is coming up in May. And I had this idea to round 55 and up year old men to play soccer with my dad for his birthday at public park. He told me last time visited that he wanted to join a soccer team in area, which he hasn’t gotten around. He is retired and his not super “peoplely”. Those dad’s that laid back and funny.
Suggestions of how one can achieve this? 🙂‍↕️

Thanks 🙂
