Hi Andreas
What you need to do is to ask Softrak for the name of other consultants, or you could contact them yourself (
http://www.softrak.com/resources/resellers.php).
I generally will take on another consultant's client if the client is unhappy, unless they owe the other consultant money. I think others feel the same way.
In my opinion, you should stick with someone in Canada, or else I'd recommend myself

Good luck
Steve
