playing with plow idea

[MikeTA95]

I never considered a plow before, but an opportunity presented itself to me this week to obtain a used one. I was going to post on plowsite but I didn't want to register for one question. Someone near me is selling a gmc 2500 sierra with a curtis plow attachment. He told me he would sell me the entire set up for $500. He said it needs nothing but a new set of pucks and maybe paint, plus its missing the driver side light (smashed out). My truck is a 1500 silverado. Does anyone with experience think that this is a good deal for me? is it possible to plow driveways with this (such as a cement driveway with a garage)? I think that I could find a lot of customers to plow for, as a matter of fact a doctor I know told me he would fire his guy if I was able to do it. Any help or advice is appreciated.
