I just installed a custom wood hood w/liner. After "much" deliberation I ended up ordering it from Prestige America. I'm not sure if they have the shape you need, but they were pretty quick in delivering it (although, you would have to check to see if they could meet your deadlines). I ended up going with them because I needed a hood liner that was 46" wide by 18" deep. I didn't want the hood to stick out farther then the stove and the finished hood comes in at 22" deep. I also wanted 1200 CFM's variable speed, and baffles. I have been really happy with it so you might want to check them out. I never considered the lighting as an important element, but the 48" has three lights also adjustable and is something we use alot. I live in California and they are made in New York. I called them directly and let me order directly from them as opposed to going through a dealer. It was a bit on the pricey side, but looks and works great. Hope that helps and good luck.

Try Modernaire. Standard liner ships in 5-7 wrkg days. Custom in 7-10. I've found them to be nice folks w/ an excellent product.
