Just use a VPN service, not a proxy which likely wont have the bandwidth you need. It is a couple of bucks a month.
As for the American address and credit card, I am not sure how that works with netflix. Doesnt it boot you over to the right service during sign up based on IP address? I would try to sign up through your VPN connection and see if that helps. I would be interested in the results of that.
Also, it isnt netflix fault about your lack of selection. It has more to do with the content owners and there BS policies and restrictions.--
