In reply to deanr: Im in IT sales and had to work hard to get into it from the medical industry (I also used to be in insurance many years ago).
As with any careers change, you need to understand the players and get to know the recruiters and there are many in IT sales. Google will help you.
my first prt of call would be to SalesForce, one of the most successful global IT CRM (cloud) platforms - my company uses it (13,000 employees) and so does my wife's 30 employees.
