Funny, I think I'm the anti-you. I'm thinking of leaving the low paid flying job for something, preferably in personal finance, so that I can finally make some headway to having a good QOL and money to save for retirement. That said, I don't necessary think you should not do this, but....
I would not drop everything, move your family, and attend one of the high dollar pilot factories. There are plenty of options for you to get your ratings quickly, but with less expense and you shouldn't have to move or give up your decent income stream. Get the commercial and then with your contacts you should be able to drum up some ideas for flying on the side so you can get a feel for what it's really like before you do a complete 180 with your life.
I'm hesistant to quit flying, because it's really all I know. I'm not particularly satisfied with it right now, but I still have visions of a reasonable future in aviation that may or may not pan out. I really only seriously consider getting out because I have an automatic ticket (as much as they get anyway) back in (furlough recall). I strongly suggest you leave yourself a "back in" (or if you can put the biz on autopilot and keep that going while you go full time into flying all the better).
Good luck.
