Find Lock Rekeying Professionals in Las Palmas of Gran Canarias, Spain

I'd like to make my balcony safe for my cat so it can't jump or slip through the railing. The balcony has a white railing and open sides, and I want a secure netting or mesh solution installed that looks tidy and doesn't block the view too much. There are a few anchor points needed around the walls and railing, so I'd appreciate advice on the best approach and materials. I'm looking for someone experienced with pet proofing balconies to handle the installation.
