helper/shop laborer in southeast Wisconsin

I'm looking for a spot as a helper or laborer in a machine shop while going to school for machining. I'm 25, live in Kenosha, Wi and have a solid work history, having worked in construction and currently working at Case New Holland on the assembly line. I need slightly more flexibility in scheduling than they can provide at this time. I attend Milwaukee Area Technical College and am working on a diploma in CNC setup and operation and plan to pursue a further diploma in CNC programming. I finished my first semester and am holding a 4.0 GPA.

I am looking for a spot that can start around 4:00 in the afternoon once classes start. I can work weekends. Willing to work anywhere in Kenosha, Racine and Milwaukee counties, and northern Illinois. Some forklift experience. I can provide as many references as required.
