Under 2 are is not very big. However, just how overgrown is it and with what?
Any large trees? Is there road access? Etc.
Who actually owns the land? Are you leasing it? If so, I’d ask the actual owners for a recommendation.
Without seeing it, I’m guessing it
might take a couple of local guys one or two days to do the job, including removing the stuff..
Cost is negotiable - Canggu is sort of an up-market area and “workers” could ask/expect higher payment than in other places. Ten bucks a day each is pretty fair (IMHO) + some snack food, coffee. If they don’t have their own transport to cart stuff away, they’ll have to rent something. That
shouldn’t be all that pricey, especially if they’re Balinese. On that note, a couple of Javanese workers would probably do it for less, if you can find some.
Hope this helps.
