There is an Assent /Andover office is Southfield Michigan, but this does not mean that I am recommending them. If you PM me then I can give you their phone number, or you can get it by going to the Andover/Assent web page and searching around. Bright trading also has an office in the Southfield, MI area...if you can come up with the higher amount of capital they require. I have been looking for firms in this area for a while, but have decided that I will probably have to trade remotely to get the right deal for me.
