What is the best moving company for a move from Brooklyn to Washington, DC?

I have contacted over 30 moving companies that I found using Yelp and Craig's List, both in NYC and DC. Quotes have ranged from $600-2,800. My last move was a nightmare even though it was just from the Bronx to Brooklyn, so I want to make sure this move goes as smoothly as possible since it's long distance. so I'm exhausting all my sources and asking for any and all recommendations for moving companies.
