I'ved used Carolina Pro Lawn Care for several years now (I'm in HS also). They mow my lawn bi-weekly and also do fall cleanup and spring mulching for me, and Robert is fairly responsive to any request that I made. PM for additional details if you like.
Since the contact info wasn't provide in the previous post, just wanted to pass it along.
