Earn Money with Appliance Hookup (Electric) in Verona, Italy

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.
