Need remote IT support for software issue and maintenance

I'm looking for a reliable IT specialist to help with a software issue on my business computer. The job involves diagnosing a recurring error message, performing basic troubleshooting, and applying necessary updates or patches. I would also like guidance on improving system security and routine maintenance to prevent future problems. Preference for clear communication, a quick turnaround, and explanations at a non-technical level. Remote work is fine, but I may require a short on-site visit if the issue persists. Please include your hourly rate and estimated time to resolve the problem.
