What does it cost to replace an oil pump with parts and labor?

Timing belt needs to come off to replace the pump housing.Might be a great friend , ........... but how well does he/she know Kia engines? checking on-line (@ autozone) cheap crap parts(my opinion) you would be starting at at least $400.00 parts & supplies ONLY , no labor cost yet......... Just a thought to try to save money and frustration...........Have it checked/diagnosed , (.......$$$..MAY save a lot to spend a little) at an independent shop (not a chain store type repair center).
