Hello, I am looking for an experienced person to help with wallpaper installation in my living room. The room is about 20 square meters and has smooth walls, but I need someone who can handle the prep work and ensure the wallpaper is applied evenly without bubbles or wrinkles. I have already purchased the wallpaper, so you just need to bring the necessary tools and expertise. Ideally, I would like this done within the next week. Please let me know if you have experience with wallpapering and can provide references.
