Cheapest way to fix my lexus skid plate?

So I ran over a curb in my 1992 lexus and it knocked the skid plate loose. It's just the front part, but it dragged along the road until I could pull over and stop to stick it back on with duct tape as a temporary fix. What can I do about it now? It's bent up pretty badly, but again, it's really just on the front. I'd like to avoid going to a dealer or an auto shop, since it seems like everything gets grossly overcharged.
