Hello,
We are an UK-based Internet Services Provider and dedicated programming company. At our company, we currently manage lots of dedicated servers, and the error shown on your screenshot seems like hard-disk damage or partition corruption. We've already done this kind of jobs, but you need to understand that if we're right about the hard-disk damage/corruption, there's a possibility that some of the data is already lost. We know lots of techniques to recover this situation and we can develop a disaster plan recovery right away. This kind of jobs are pretty slow generally, but keeping in mind that it's a production server and there're live websites running right now, we will do our best to recover it quickly and without further damage to your users.
For this project, we can dedicate a highly professional team so you will always get the highest quality on the final product, always supervised by our Chief Technical Officer, who is aware of which technology, how and why should be used in any given project.
If you need to discuss anything about our procedures or any other specification of your project, just drop us a message.
Kind regards and thanks for choosing us.
