Need help cleaning and optimizing my computer effectively

Hi there, I'm looking for a careful technician to clean my computer and boost performance. It’s a mid‑range PC running Windows, with a couple of years of files, photos, and installed programs. I’d like a thorough software cleanup (removing junk, malware scan, outdated apps), temporary file purge, and a lightweight hardware check (fans, thermals) if possible. Please provide guidance on optimizing startup and general maintenance. I prefer a friendly, non‑techy explanation and to work remotely if you can, but I’m open to a short on‑site visit in Dublin area if necessary. Budget is flexible depending on scope.
