If you haven't already check put workaway.info and help-x.com. both essentially the same thing. Workaway is more popular in Europe and helpx more in Asia/nz I found.
You can browse all the listings for free and then pay a yearly cost of around £25 for contact details if you find something. I used helpx for a year in many different places in nz and was great! Also used workaway to find a hostel in Iceland where me and friend stayed for 5 months, just doing 4 hours work then splitboarding the rest of the time. Also amazing!
