Data Recovery 2

I want to get files of my old broken hard drive, anyone know a reliable cheap data recovery firm in the UK?
Basically it stopped being recognised by my mac. I took it to my local computer shop which had a good look at it and said that the problem was between the caddy and the hard drive but that the hard drive itself was fine. I have kept the hard drive in dry place for about 2 year and now have money to try and recover the contents.
this helped me to recover my files
