Ubuntu/MySQL server crash - retrieval or repair

Job ID: 35556218

Budget: £20 – £250 GBP

I have an unmanaged server on Hetzner Cloud - server crashed and databases went down and will not restart. I can't find any way to get at them or even if they're still on the server but would like to be able to retrieve if possible to reinstate a couple of Wordpress websites. I have SSH login.
