Need help with a miscellaneous IT task in Ireland, Dublin

Hi there, I’m looking for a reliable person to handle a small, general IT task at my home office in Ireland. The job involves diagnosing a quirky software issue, doing a quick clean-up of my computer, and setting up a backup routine. I prefer someone who can explain steps clearly and avoid technical jargon. It would be great if you could bring a USB drive, a spare external hard drive, and have experience with Windows or macOS basics. Availability during the morning hours would be ideal. If you can help with a quick remote diagnostic first to save time, that would be a plus.
