There are different Linux distributions that do offer paid support, as far as the OS goes. So if you're interested in professional paid support for the OS, something like Zorin OS or Ubuntu may be an option. I've seen others recommend Linux mint, and that's my go-to for someone not familiar with Linux. It's popular and even if whatever repair shop you're taking it into isn't familiar, they can find the resources online to fix whatever problem you may have. But being totally practical, even if you dislike windows, if it's able to do what you need, and the people that you know are familiar with it, is it worth the effort to swap for you and your use case?
