You will get a much better response if you post in an actual city/town instead of the whole state.
We live in Northville but we are open to something outside of Wayne County if it was what we were looking for.
Maybe Cobblestone Farm in Ann Arbor? http://www.a2gov.org/government/communityservices/ParksandRecreation/Pages/CobblestoneFarmCenterRentals.aspx
also, we had our reception outdoors at Concordia College - rented the historic manor (Earhart Manor) on the grounds of their campus and had a tent set up for 150 ppl...depending on food you might spend more than $7500, but the rental itself wasn't nearly that much. http://www.cuaa.edu/AboutCUAA/earhart-manor.html Good Luck!
