Tile removal and wall repair

We are about to renovate our kitchen, and i need to have the tiles removed from a concrete wall and the wall smoothed. (To simplify the process, i can handle the painting myself afterward.) The area is approximately 3. 7 m². i can send a picture if that helps. i only need the tiles removed and wall repaired. The ideal timing would be some time between 26 October and 4 November. Could you please provide a price estimate for this part of the job? The job would be done at Turbinveien 21, Oslo.
