Hi there! I'm an international student too and totally understand the frustrations & costs regarding evaluation of foreign credentials.
I'm using World Education Services (WES-Google it!). The process is a bit cumbersome but there is absolutely no way around it, at least on my case (applying for an MPH through SOPHAS). But anyway, the initial 200 bucks or so is for the evaluation of your transcript as well as a fee for sending out a copy to your desired institution and one for your own keep. Additional reporting will cost more money about $30 per duplicate, much less than $200!
Hope that helps!
