Hi, I recently bought some shelves that need to be securely fixed to the walls in my living room. The walls are plaster, and I want to make sure the shelves are properly anchored to hold books and decorations safely. I have all the shelves and brackets ready, just need someone with the right tools and experience to do a neat and sturdy job. Ideally, someone who can come during the day and finish within a few hours. Looking forward to your help!
