...and before you pick a company, do your homework. There is a number of fly-by-nighters who have no clue what data recovery is. Cute and fancy website is an easy catch these days. Don't fall for its appeal, talk to the techs, see how well the conversation goes. Don't settle for the cheapest quote. A good engineer pays higher bills for his "better" equipment, so if data is important, make sure it's done right by the reputable data recovery engineer. Remember, sometimes there is only one attempt and it has to be done right.
Best of luck!
