Need help installing interior window blinds in living room

I recently bought new interior blinds for my living room and could use a skilled hand to install them properly. The windows are standard size, and I want the blinds fitted securely, level, and trimmed to fit. I’d prefer a tidy finish with minimal wall damage. If you have experience with different mounting options or brackets for heavy blinds, please let me know. I’m hoping to have this done soon, ideally on a weekday morning. Please include a quick assessment of any tools or extra supplies you’d need from me.
