Need help installing kitchen backsplash tiles securely

Hi there, I’m looking for a skilled handyman to install a new kitchen backsplash (standard 60x60 cm tiles) over a tiled wall. I want a clean, professional finish with evenly spaced grout lines and no uneven edges. The work will involve measuring, cutting tiles as needed, sealing edges, and ensuring watertight joints around the sink area. It would be great if you can supply or advise on suitable tile spacers and adhesive. I’m aiming for a neat, modern look and would prefer someone with experience in tile work. The job location is in London, and I’m hoping to schedule for a weekend or weekday afternoon if possible. Please let me know your availability and an estimated quote.
