Need help installing interior blind/curtain store indoors

Hi there! I’m looking for someone to install an interior window blind in my living room. The setup involves a standard sized window (approx. 120cm wide) and I already have the blind kit with mounting brackets and screws. I’d prefer a tidy finish with minimal wall damage and would appreciate a quick, clean job on a weekend if possible. If you can supply basic tools and confirm compatibility with plaster walls, that would be great. I can provide photos or measurements if needed and am happy to discuss any preparation I should do beforehand.
