Tiler Job - Milnerton Ridge, WC, 7441

Some of the tiles (about 15) on my kitchen wall has come loose, so I took them off. I want the same tiles to be attached to the wall again. They all have cement on the back, which will have to be removed (very carefully, because I can't replace the broken tiles). There is also uneven cement on the wall which will have to be removed with a grinder or something. I have no tools. I might also need some handyman work done. It's a very small job. The rivet on the mechanism that opens and closes the kitchen window (it opens from the bottom) is broken, so the window is not secure. A rivet gun might be needed. I will try to fix it myself, but if I can't I will need your service. But the tiles are the main thing. Do you charge per hour or how does it work?.
