You are asking for a committed and responsible employee to work 40 flexible hours a month for 200 dollars - then pay you back 100 dollars.?
Although they do get a room in a communal flat. Doesn't sound like deal of the day really.
If you can't get a local, maybe you can cast the net further afield. Some websites cater for wanderers who barter work for accommodation. Otherwise you can rethink your proposition with the property to make it more viable.
Airbnb closed down the co-host marketplace regrettably, but there are a couple of independent websites that try to get hosts and potential co-hosts together out there. Try there too.
