I think Linux Mint needs to implement professional support services through:
1- Official documentation (Like fedoraproject.org)
2- Support websites (like ubuntugeek.com)
3- Online support (like ubuntu.com/support)
This should be available on the official website.
Actually I have come across many highly skilled professionals on Linux Mint forum who can do the job.
