hi waddo, just to be clear, is this the part of the bike you are referring to?
I gradually acquired bike mechanic experience over a good 35 years, bit by bit, and can attest to what someone else mentioned--that sounds from this area can be a few things, so if you have an interest to investigate, you need to methodically go through the steps to see what part is making the sound.

Bottom line, a bunch of us would be very happy to help you with this, but online typing and not being by your bike makes it pretty darn tricky.
We'd love to identify your sound, but can only do so much.
You don't have the tools to do it on your own, but if you do have an urge to learn some bike mechanic stuff, the Parks Tools video series is a great source of well shot, well lit, well hosted series that can help you get some visual explanations.
Question--do you have any interest in doing this repair yourself? My guess is no, so I suspect getting to a larger urban area with a known bike store will be your best bet for a repair, but still would be good to identify whats making the sound.
are you interested in working with us for that, via a 12 hr time difference?
