Not a good idea.
In the hole state of Arizona, you can probably count the number of people making a living off small mining on two hands.
So I would say, no don't quit your day job.
I have been to dozens on places, if you have any around Wickenburg, I may have even been to the ones you looked at. None of these panned out in the day I spent at each of those places. I found a lot of copper type minerals from mines located prior to strip mining, but there's no way to make money off coper as a small miner.
I have met a couple of people who did something like you were saying and moved down here to mine gold as a primary living, and did not make any money off it. Lost plenty. I also know a lot of people that will show some gold of what they've found, but often its a season's worth, or year's worth, or even a lifetime's worth, but never enough to pay the bills. I met a couple in Lynx Creek that was falling behind in bills, so decided to spend their time panning at the creek to catch up. At the end of two weeks they showed me a grams worth, $30. They would have been better off never heading out there.
Some people will try to tell you otherwise. Be very cautious with any life decisions.
