anyone have a referral to stairhopper (or another) movers?

Hi! I'm moving soon (within Boston) and just wanted to see if anyone had a referral to stairhoppers and/or another mover that could get them and/or me a discount. Also, if anyone has any experience for how much it cost them to get movers from one bedroom on the third floor to another bedroom on the third floor of another nearby apt, it would be great to know :)
