How do I transition into a new field?

I am 27. After working long hours as a cook, I have developed a tear in the rotator cuff from repetitive stress. Before culinary school I briefly worked as an Account Manager, so I have some sales experience, but it was a while ago. What sort of entry level office jobs can I apply for?
