Sorry I don't know of anyone to do that work but I am sure once down there it would be easy to find. Javier has a way of finding these things out. There is a really good bodyman and painter in cocula. He has done some great work for us and friends. When will you be at the park? Come see us and we can talk about it.
You would be able to store your rig in Chimulco for the summer. It would be way healthier for the rig away from the humidity and salt. You could still do your month there before you take care of those itchy feet.
