Jazz Jams

I am looking to start up weekly or biweekly Jam sessions open to any abilities and instruments.
Who would be interested in establishing a jazz or jazz/blues jam session on the North Oakland County, Genesee County or Lapeer County area? I am looking for places that can accommodate up 30 to 40 people.
Depending on the level of interest and willingness of others to participate and maybe even help put something together, I’m considering renting a small place.
