Kicking around the Idea of full timing but I need help.....

So we have thought about full timing multiple times but have never really landed on it because of $$$$. I have read about and watched people make this decision but they are usually some kind of internet worker or freelancer. So here is my question. Is there any families out there doing something different and making enough money? Right now I make a little over 80k / year and I would love to find something that pays the same or more to be comfortable full timing. I understand I wouldn't need as much but we spend most of our income on food because we try to eat healthy and have a family of 6. So any ideas on how to make decent money out there. I'm a pretty handy guy that usually does everything DIY. Thanks in advance.
