I have not personally had any done by Mark Frappier, but the shop I worked at for a while had him sleeve a number of cylinders while I was there, and I have seen first hand the nice work he does. (I am a machinist by trade, and know good work when I see it)
You will have to call him for prices, but my recollection is he was very fair, and many times for the older vehicles actually cheaper than new, and the longer life of stainless is a huge bonus. I would happily pay more for stainless sleeved cylinders than original cast ones if given the choice.
