Headliner board replacement/fabrication?

Hey all, I'm new to the forum and was hoping to get some input! I have a 99 GT with a sunroof and my headliner board is thoroughly shot. I've been looking around on the net for any sort of replacement board but have had no such luck, so I was wondering if anybody here has attempted to fabricate a new board and if so how did you go about it? Any info would be awesome!

Yeah it is the actual board itself. I was kinda hoping that I wouldn't end up having to take it to a shop but theres no doubt that they would do a better job than I could! Just hope it wouldn't be terribly expensive.
