Are you able to live in the Florida house now? If so, I'd say start your gardening and herbal business in PA now and go to FL in the winter and start one there. You may be able to get someone to run it in FL whle you're traveling back and forth between the two states and hopefully making stops to sell on the way. Also, have you considered buying/renting a camper van? They are less expensive to buy or rent and will use less gas. Or if you have a pick up truck, you could always get one of those campers that either attach or can be towed. Then once you're old enough to draw Social Security, you can decide if/what to sell.
