Chicago - Board up costs

[Brian H.]

Hey folks, does anyone know how much a typical board up costs in Chicago? Say, a one story (with basement and attic) SFH with 3 exterior doors and 9 windows. Something like 6939 S. Laflin.
I'm curious how much a typical board up costs, just to put plywood over everything and secure it, vs. using something like DAWGS with their operable steel doors. I assume DAWGS is an install fee and then a monthly fee? 
Anyone have some rough estimates they could share here? 

Thanks
