I cast a line out there today to see if there might be any Japanese climbers who might be able to help you out for awhile, or more permanently, wanting to go to the states. I only know one guy who might meet your requirements, and he is currently employed, also has a wife and young child. I worked with him one day, don't know him so well, but I asked a mutual friend to mention it to him, and also as to the possibility that he might know somebody. I don't know if you are even remotely interested in that type of situation, but figured that it wouldn't hurt to see what might turn up. No prob if you don't want to consider it for any reason, there are definitely different logistics compared to having a local guy. No doubt there are climbers here who would love to go to the states to further their experience. Have to be an illegal I guess, no work permit.
