Island Lake has Sporting clays, skeet and trap. Right down the street from you(96 to Kensington Rd. S., to Grand River E. can't miss it). Its $5/round of trap and the pullers there are very good at helping out new shooters. They will not make you feel like a spincaster on a river of flyfishermen. Barrel length must be 26"+ and shot no larger than 7 1/2 .
Go through the clubhouse and straight across to the trap range. THey have benches where you can sit and watch to get the idea. Someone may even offer to help you out.
Sharronville State Game (Manchester area) area has a public range that has an area set up for clay games. Basically, its concrete bases for you to set up your own thrower and shoot whatever you want on their field.

Multi Lakes Conservation Club in Walled Lake - (248) 363-9109. Its a private club but you might want to contact them. Its possible they have a class for beginners that is open to the public.
Wayne County Sportsmans Club is open to the public and their trap shooting is casual and friendly. Its a hike from your neck of the woods but its cheap ($4/round) and its a low stress place to shoot. Its in Romulous/Inkster area, South of Detroit Metro airport.
Then there is The Pit. Its Federal land in Lapeer that you can target shoot on. Its not a range. There is no supervision but the folks that shoot there are pretty good about safety. If you need directions, let me know.
HTH,
