Cedar Rapids is a city similar to Peoria, except the crime is very low. Maybe 1-2 homicides per year.
I'm not sure how you found a 5 bedroom place for $700/mo - that is cheap! Probably wont find that here unless it's in a run down part of town. The great thign about CR is that you can live almost anywhere you want and feel safe. You wont have to dodge any bullets!
The major employers here are Rockwell, Aegon, Quaker Oats, General Mills. Rockwell employs about 10k in the CR/Iowa City area. But these employers are NOT the only places to work. Cedar Rapids has a very diverse economy that you should be able to find a professional job in pretty easily.
Or you could work in fast food too
