We used Professional Moving Solutions for a local move in the Tampa area. They quoted 9 hours but the guys were so inexperienced and tired from finishing a move from the night before and working on 2 hours sleep that the move took them 15.
First of all beware of the upcharges on materials. Our estimate doubled when they arrived at our house. Lucky for us we had our own supplies or we would have had to pay $1000 more for shrink wrapping every item, which doesn't protect against rubs and dings on the furniture and is a scam by PMS.
The 4 movers assigned to our job argued most of the day about which task each one was going to do. They were all tired from a late move the day before and were working on less than 3 hours rest between jobs. One mover even had to take a nap in the cabin of the truck during our move. The truck loader didn't know what he was doing and had to unload everything after about an hour on the job and start again. One of the other guys was unbelievably disrespectful when talking to my teenage daughter after our move ran 6 hours over due to their lack of leadership, experience and teamwork. I tried to work with customer service but have yet to receive satisfaction.
