Killer bass player? Yes.
Set up whiz? Not on your tintype.
Techs don't work the way Gary Willis does because it is inefficient and does not produce the desired results in a timely or repeatable way. That's the reason his website link is no longer listed in the sticky. Not recommended.
Being new to set up, sixty two pages of reading (it's an easy read, by the way) is a very small price to pay to learn how to do it right. Besides, it's free. Or you could spend thirty dollars on The Guitar Player Guide to Repair by Dan Erlewine. At three hundred twenty two pages, it is comprehensive. It is the book that most of the guys who have been in the business for the last thirty years use. A good tech probably has a copy on a shelf near his bench. The book is still less than the cost of a good set up.
As far as whether or not the OP should be seeking a mechanical solution for what might be a technique problem, it is impossible to ascertain from his postings. Data is key here. Relief and string height will go a long way to solving this.
On the other hand, some pro's slap and pluck with amazingly high action, more than 8/64" (~3.2mm) and have no problem making it sound great.
Others require incredibly low string heights (think in terms of half the above) with super flexible strings and can still play quietly. It is difficult to diagnose from a distance.
