It would cost way too much for me to do them for pay. I honestly would love to do it, but I am just too busy to find time to make other people's sills. It took me weeks just to do mine. It will take many hours of labour, and is easy to mess up. I would have to charge ALOT to do it with my methods. I might eventually try to get a machine shop working with me to do them. Then it would be much cheaper!
If you think you could, give it a try! much cheaper to do yourself.

hey man how much do you think you would charge to do the sills if i shipped em out to you...i want a led white color
