Referral for professional-looking headshot?

My boss has asked me to have a professional picture taken for our website and I've been meaning to have one taken for used on LinkedIn - anyone know anyone who can do something like this for a reasonable price? I've gotten a quote of $300.00 from one person but that's waaaaaaaaaay more than I want to spend. Anyone have a friend of a friend who's handy with a camera and could take a professional-looking shot or two of me in a park or something?
