The guy that would be my first choice is. No phone, interenet and not much interest in communicating with humans.
The main problem is language. The rural Catalans tend to speak a mixture of Catalan and Spanish. I don't speak any Spanish and my Catalan wasn't great and now it's rusty and not great.
Rural Catalan is about phrases. It's not much like the Catalan one would learn in a class.
An example of how easily things go wrong.
I had a mite problem with a sitting hen. I tried to explain to my friend what the problem was. Eventually I showed him some pictures of the hen in question. He told me the problem was spiders! I looked for spiders which have eight legs and in my limited knowledge are large enough to see with the naked eye. Couldn't find any spiders.
Had another go talking to him. He insisted that the problem was a very small spider. Eventually talking to another friend who spoke fair English I discovered there is no word for mites in Catalan; they're called spiders.
Once I got that, the rest didn't take long and the culprit was a mite called Straw Itch Mite that lives in Hay.

Another.
Ask how to plant garlic and you may get told that the garlic must see you leave the field.

What it means is don't bury it.

Now mix in a bit of Spanish and the rest of the problems associated with distance communication and it could take weeks to get an answer that makes any sort of sense.
