I run a web hosting service, work here full time and have extensive server troubleshooting experience, so I can get your mysql server running again.
As with all corruption issues, some data may be damaged even after the server comes back up. Best course of action is to restore any damaged databases from backup.
Bid covers in-server troubleshooting. If needed, I will pull the entire mysql setup and run Phoenix recovery on it, but at an additional $100.
