Seeking Recommendations For A HDD Data Recovery Service.

I hope this is the correct forum.

An external HDD of mine packed in on Thursday.

I am trying to restore to the replacement, but my offsite backup solution is both very slow, and it might be that it was not backing up everything I thought it was.

So I am considering a data recovery service. I found a few companies in Switzerland via Google, but does anyone have a company they can recommend?

I know this is not going to be cheap.
