We found a great fulltimers site,
www.rv-dreams.com , where they discuss their own finances in great detail. They started fulltiming in their early 40's which is what we are hoping to do and their site has been a valuable resource. It's not a financial planning site, but discusses
their investment dollars, budgets, plans for income, etc.. It's worth a look and probably more. There is a link for 'Financial Information' on the left hand menu. They have been very open which has made us realize that we could do it too.
