I don't know how the guys here feel about Bartlett but I worked there for a year and the some of the guys are still there I climbed with, really good guys. Give them a call, they are in Springfield, VA, and try to make sure Brian Lacey is the one that comes out to do the actual work (you will get someone else to give you the quote). I worked with Brian a lot and trust him, I would want him if there was a tree to remove from over my house and I was unable for some reason (and yes he is a certified aborist). Good luck and if you are looking at a company feel free to ask about them we may be able to give some warning.
