Never have your Accountant as a Client
Never ever take on your accountant as a client, the bastard will be able see how much money your making & will always always try to cut you down. I made that mistake once, never again. I have an understanding with my current accountant that should he need to change his IT Support company I will gladly help him find a replacement, but it won't be me. If he decides he wants me to do it then I will have to find a new accountant.
Back on Topic, many many moons ago working in a PC repair shop I was tasked with getting the data off a failed drive. I got to the point of sending it to a specialist as the customer was happy to spend the £600 or so quoted, filing out the form it asked if the failure was mechanical or electrical, so powering up one last time I heard a clunk clunk, to this day I don't know why but I gave it one almighty whack on the workbench, it burst into life just long enough to ghost it to another drive.
One happy customer and we made an extra £600 that day :-)
