Outsourcing Cleaning and Sanitation

I am looking to hire a service to clean our production room after hours.

I currently have one line and we tend to shut down almost 2 hours early to clean and sanitize because the crew I have is the crew I have to do that as well as run production. We need to come up with a more thorough cleaning procedure as well because when their day is over, at times things are left undone.

Any recommendations for services near Chicago, IL that can do this? 

I'm thinking once a week after hours for 2-4 hours they would come in and do the clean. Maybe once a month do warehouses and a more thorough job.

Thanks

I don't know if you started with a quick google but I see SaniKing out of Chicago and a OSS from Bensenville.  Also I have worked with PSSI here in MN but they have outfits all over.
