Trying to settle on a tank removal service

I'm the secretary for a small company, and my boss told me to find an oil tank removal company. I just started this job so I'm not familiar with local companies and I'm stressing out about finding the right one. I used to live in Hyannis so I've heard of this company before but it's not in the location I moved to. Luckily, Patch.com has been a huge lifesaver for me in helping me locate companies near me. http://www.emaenv.com/index.php/oil-tank-removal/
