Earn Money with Kitchen Backsplash Installation in Greece

I want tiles to be installed throughout the 47 sq.m. apartment on the floor, as well as on 18 sq.m. of walls in the bathroom. The apartment is located in Piraeus and is empty, ready for work. I will supply the tiles myself, but I need a professional for the installation. Please calculate the cost based on the square meters and let me know if any preparation of the space is needed. I am available to discuss the details.
