What is the price range for engine work on a kia rio?

I have a 2001 kia rio that needs work on the cylinder block I went online to see how much a new one would cost and it is in the $700 price range.A new engine would only run in the $1000 range how much would a mechanic charge for the work for either part versus taking the car to the agency?|||It would depend on the amount of work your actual engine requires
