iframes do not work
I am not suggesting inline frames, but total site framing with the title and description meta tag under the main domain name. This should work unless there is competition from other sites. You don't have to pay for monthly hosting to do this normally.

And on the target site that is framed, you can use PHP to alter the content according to the referring domain name.

Then, if the site is profitable for traffic from the country of the domain name, you can set up a dedicated hosting account in that place, safe in the knowledge that it will be profitable.
