Mail Contractors in Michigan

I am looking to make a change and try my hand running the mail. Thing is, it is harder than you would think it should be to do a job search now a days. All the big companies are flooding job sites with ads in every city & category. Basically what I'm looking for is the following:

Who are the mail contractors for the following areas; Ann Arbor & Lansing?

Where are they based out of for those areas?

What are their web addresses?

I know B&B Trucking is doing the Kalamaoo area stuff, and have questions about them, but I will be making a separate thread on them as to keep the threads focused.

Thanks for your time.

 

Thanks, I will try & find that 1st company.
