If he is still available and convenient I'd ask papajam to do this job too.
I have used White Post Restorations to sleeve and rebuild cylinders in the past; with great results. They use a brass sleeve as opposed to stainless steel but you'd be hard pressed to feel the difference. The part is returned completely rebuilt and refinished, inside and out, ready to install. They offer a lifetime warranty on all their rebuilt brake parts too (not for DOT 5, Silicone use though).
