I submitted a quote request over the Web to NESS and a competitor. Both charged the same amount for one-time residential pickup. I chose NESS because Mac (an employee) called me while other place sent e-mail, he answered all of my questions (e-mail from competitor ignored them), he was flexible (arranged a pickup at my home while I was at work), communicated terms clearly, and confirmed pickup and payment details to ensure the transaction went smoothly, which it did. I will definitely hire these guys again.
