Would it seriously help what?
Are you asking if obtaining your mechanic certificate would help you get a corporate pilot job? If so, then you're probably barking up the wrong tree.
Are you hoping to go from flight instructing to a "sweet corporate gig?" You may also be in for a surprise.
If you want to obtain your mechanic certificate to learn more about aircraft and become a better pilot, broaden your understanding, gain new work skills, and open other avenues of employment, then you're a good candidate for maintenance training. If you're looking to pick it up to boost your resume, then you're probably setting yourself back a year or two that could be spent flying cargo or gaining other experience that will get you into the job you want.
Chances are that you're not going to sit at home, instruct for a year or two, and find a corporate job in your back yard. Chances are that you're going to have to move several times to be closer to work while you gain the experience you need, and begin to work to put yourself in a position where you are able to make choices like where you'll work, and for whom you'll work.
You can obtain a mechanic certificate in more ways than going to school, though that's a good place to start.
