Check in the repair section, I don't know of any personally.
Although I can't see why this would be difficult to do, it's essentially a "reverse transplant"
They would have to draw out an acceptable balding pattern and then just laser everything inside it.
If you want to see what it would look like I suppose you could do the same thing at home and just pluck the hairs in the desired area so you can get the effect you want before resorting to the permanency of a laser.
