You do not provide your age. For all ages, try U of Mich ballroom dances Sunday evening in the Michigan Union Ballroom in Ann Arbor. Non profit, run by students, welcomes all. From talking with others, you can find many studios.
Michigan Swing Dance Association, www.msda.org, (also nonprofit) is sponsoring their first big dance Saturday, Oct 15, at the Masonic Temple. There is a higher than normal charge ($25) but they have three ballrooms simultaneously, bands, DJ, Showcases, etc. Several studios will be represented. The Lindy and Salsa will draw the younger crowd; ballroom the older.
I go to studios in Centerline and sometimes Bloomfield Hills (non franchise). Some prefer Troy, West Bloomfield, Dearborn, Saline.
Dancing is like any exercise. You must make time for it.
