not sure what exactly u wanna do with ur engine, and cost'd vary. e.g.
1. just putting upsized rings while doing nothing on cyl block/crank/pistons
2. sticking sleeve inside cyl area
3. doing a complete over haul, piston/rings replacement, crank/cyl machining etc n other costs involved are pressure/clutch plate, water pump, timing belt/chain repl.
it'd be good idea if u visit ur local market and get prices of parts and add labour charges.
