Full disclosure: I AM NOT A PRO and never will be.
However, I am also a DIYer. As long as your willing to learn and do it right this could be accomplished by someone with reasonable skill, intelligence. and patience.
There are quite a few gotchas to be aware of however. The PVC fittings you will eventually use must be for the purpose for which they are intended, sink venting must be considered, drain line sizing must be proper, and heights must be followed for traps and drains. If your water lines are copper or pex these will need be run and connected too. Drywall work will be mandatory, so think along those lines also.
If you considered using the existing cleanout (plugged) as the utility sink drain input you have some reading to do.
Before calling in a 'pro' I would educate myself as to what is really required and then get some quotes from a few. Then, if they lead you astray I would look elsewhere. It may work, but it wont be right (or to code).
If you decide to take this on, just know where your going before you start. And ask questions, both here and elsewhere.
