East Coast Retinning does it for $4 per inch, "inch" defined as 2 X height + 1 X diameter.

They strip off the old tin, remove any dents, polish the exterior, pour molten tin in the pot and brush to coat. I haven't used but have been studying their website since have two copper pots that need this work.

My friend tried a home retinning kit, the problem is the unevenly worn old tin surface makes the new tin surface also uneven.
