Should be able to do it yourself with the right tools. A drill, a £10 jigsaw, a diamond core drill bit and a grit/diamond jigsaw blade. Put some packing/masking tape over the surfaces you're going to cut, to avoid chips. Use the diamond core bit to make the hole, and use the jigsaw to cut the shape. You can use the same setup for cutting tiles & stone. Wear goggles!
