My shop will machine the entire block for a little over $500 and that includes some of the new bearings I will need. To sleeve one cylinder is less than $200. But they cannot just sleeve it and walk away. They have to check adjacent cylinders for distortion, and they have to redeck the block after it is sleeved. Probably will come out closer to $300 when finished. And I don't know that I should trust the block.
I am over $7K into this engine bay already. Not going to shortcut it for a couple hundred bucks.
