Well I know this is a bit delayed but Just look into your local rotary club. If you talk to them they should let you know whether or not they send people on exchange or they may let you know of another club. Thats really all you have to do. If you know any rotarians just talk to them.
I am at the end of my exchange and thats just what I did. I got told about exchange and even though I'm not with a local club to me in Australia they found a club to sponsor me.
