Pere Marquette locomotive needs a workout

As I look over my G scale items to run next spring, I came across my #1 gauge Pere Marquette locomotive and caboose. I have been on a quest to find rolling stock for it. I prefer passenger cars however I will take anything in 1/32 scale. So far no luck what so ever. I might just have to resort to having cars custom painted. I have no idea as to what that would cost.

I have enough curved track to set up an 8ft circle, but I don't have a transformer yet to power the track.
