This is unfortuanately on the same lines of the previous poster but if you're willling to go south a bit (to bad gas prices are so high - driving back on the weekends could be rough), you could look into the following:
Kadrmas Lee & Jakson
NISC
MDU Resources
Basin Electric
Bobcat - they have a great coop program
Applied Engineering
Bullberry Systems
Unysis - maybee
and i suppose the State of ND
K2 Interactive - website design
Odeney - website design i think
Here's a website I found -
Team ND - maybe it has something in Minot.
Thinking about it, Kadrmas Lee & Jackson also has an office in Minot - they might let you do a coop there.
