The currency exchange works both ways - you'll get a boost when translating the income back to CAD.That is true, but it is also not always the best approach.  

Jon above is correct that you would be better of approaching a HML with a separate deal.

@Joshua Dorkin Are you taking the approach of Web Chat Client that is XMPP compatible {a back-end XMPP server}?

Someone approaches you and asks to get in touch with your client list so they can offer them alternative investments. 

ive never heard that approach and if it actually works i need to start walking around my town and knock on 80% of the doors. lol I really am curious about this method.. has it worked for you in the past?

Is there any other way I should be approaching it?
