Need to change the POOL Pump!

Hii, I bought a property in Massachusetts. There was a pool which was built at the time of the home construction, that was 3 years back. The pool is of a size 32*20, well maintained(externally it is beautiful) till date. But when we drained it for cleaning, last day we found there are some issues with the pump. There is a slight leak I guess not sure anyway. We've contacted some swimming pool services in Massachusetts. So far they were good, clarified my doubts and they are ready to help us any time. But I'm new to Massachusetts, so I'm not sure about their service quality. My friend suggested that instead of calling pool boys it can be done with the help of pro plumber. I'm in chaos. What should I do now? Contact a pool guy or plumper??
