Earn Money with Electrical Troubleshooting Services

I need to move a light switch a few centimeters because a built-in wardrobe is going to be installed and right now it's in the way. The switch works fine, I just want to move it so it's accessible and doesn't clash with the wardrobe. I would like the installation to be left properly finished and without exposed wires. I would appreciate it if someone could tell me whether any chasing needs to be done or if the existing wiring can be reused.

Connecting the doorbell handset to an existing installation

I need to replace three old electrical outlets and install a new gas oven and hob. The hob measures 58 cm wide x 51 cm deep. The oven measures 59 cm wide x 59 cm high (I don't know the depth because it's recessed into the marble countertop (see photos)). I have to buy the hob and oven myself, but I'd like some advice on choosing something that fits well or can be installed correctly in the existing space with minimal adjustment (it's an old marble countertop). I can also buy the electrical outlets separately; the estimate would only cover labor.
