Hey, I'm also trying to hire coders to work on a remote tropical island [1], although for a little longer term than you. Where is this located? I can recommend some places in the Seychelles if you haven't yet decided on a spot :)
How about Pitcairn Island? You can't get much more remote. Two months fits in fairly well with the supply ship coming and going for transport to/from the island. 12 people would increase the local population by almost 25%!
My company is based in the Philippines. I won't be applying but I'd love to take you and the crew out if you're laid over in Manila for any stretch of time.
