I have a lot of experience in installing and configuing a Linux system.
This operating system is very temperamental, and requires a lot, and I say again, A LOT of manual work.
I am unable to provide anything else at this time.
This does require screensharing, or if you can, pull out your mobile device and take photos.
These will not only help me, but it'll also help you.
Due to this type of job, the price will go up by quite a significant amount.
However, at the end of the day, you will get a reliable, and very responsive system in the process.
