Hi, for something that specialised you may not find anyone here who can help (or maybe you will).
Anyway, if you struggle I recommend this site, I have used it a couple of times in the past and it is REALLY good.
You simply put in as detailed a spec as possible of the job you want and people from around the world tender quotes etc.
There is a ton more on there than simply designers so take a good look around.
You can even pay many of the people via PayPal if you wish.
It is a good way of finding the right people and if you use the site enough I think it would be an excellent way to start networking.
The address is

GOOD LUCK!!!
