Not sure of the job you're going for, but in overall skills, try to hit all of your good ones that you've picked up because of MSing. Highly organized, objective, detailed, professional reporting, resourceful, efficient, hard-working (those jobs don't assign themselves!)
In specific skills, cite your knowledge of of Excel, creating invoices, expense reports, etc.
Oh, and find a professional way to write "go-getter" because MSers are definitely that.
