I would be extremely careful in dealing with private individuals claiming to be animal brokers, be you a zoological institution or private individual trying to legally obtain an animal species.
The price tag of US$200 you have been led to believe is not realistic if you are talking intercontinental transfer, if you ask me. Think of all the paperwork and the health and veterinary requirements, not to speak of air transport and crate charges and you are looking at 1,000's of US paper money.
First of all, you should ask this individual for his written credentials and company details and procedures for dealing with animal transfers. After receiving this written confirmation (absolutely no internet confirmation as this is highly suspect), I would enquire former clients or third parties for more information.
However, - on face value - I am pretty confident you are dealing with a hoaxer and deem the whole business as highly suspect. My piece of advice: do not mess around with ... unless you are completely confident.
NOTA BENE:
1) I should stress my advice is strictly personal title and does not convey any professional legally binding assessment of the individual you claim to be dealing with.
2) I would like to make it clear that I do not condone any exploitation outside of any legal requirements vis a vis the (illegal) wildlife animal trade.
3) If it turns out the individual you claim to be dealing with is highly suspect, I would immediately inform the competent legal authority and regional TRAFFIC department so they can monitor this individual or his trading line.
4) Some legally accredited animal brokers are: International Animal Exchange (US) and EKIPA (NL-GE).
5) I would seek the advice of professional aviculturalists associations within the US for further guidance.
