Need computer cleaning service for my PC in Ireland

I'm looking for a tech-savvy person to clean and optimize my desktop computer. It’s a mid-2018 Windows PC running slowly, with dust buildup and cluttered startup programs. I’d like a thorough exterior clean, interior dust removal from the case, fans, and heatsinks, plus software cleanup: removing unnecessary apps, optimizing startup, and running basic maintenance scans. Please bring anti-static precautions, a small toolkit, and let me know if the system needs any hardware checks. Ideally done in a quiet, accessible space at my home, and I’m hoping for a friendly, clear explanation of what was done.
