Nick.... It will be all mats and all the carpet front to back. The extractor i will be using its kinda like the Mytee but its alittle bigger in size .But its a nice extractor that my brother lets me borrow. Hes a proffesional carpet cleaner and floor mant.
I think the carwash/oil change center down the street charges $10/mat. I figure it will take you approximately 75-120 minutes to complete, so $50-70 doesn't seem out of the question. This also depends on how much product you'll be using. Shoot, hit'em up for $100 for being slops!
