No time like the present to get that experience then. Like the 1911 shooter that needs to "be their own armorer" the DA revolver shooter is in the same boat. I used to caveat that as "at least, used in any real volume." Maybe with the state of things you need it out of the gate. Otherwise the answer is the same as it ever was: sell it and buy a Glock 19. This isn't likely to be very enjoyable unless you're willing to get some grit under your fingernails.
Doing things like taking the high spots off the side of the trigger/hammer, fitting a hand, replacing a cylinder stop, etc isn't difficult to learn. I don't know enough about Ruger DAs to have an informed opinion on the kevinsworkbench.com link. But that's certainly the type of place to start.
Plenty of GP-100 "kits" here. Under $200 gets you a hammer and complete (seeming) trigger assembly along with other hard parts like the cylinder and barrel you could possibly use to recover some of the cost. If you're reticent, then tinker with those and leave your original parts alone.
