I've actually looked into this. Easter European women have the mindset more of the 50s American housewives wanting the traditional American dream, you know, the white picket fence, cooking every night for their husbands, raising kids, pleasing their man... etc.
I've found this to be the biggest, most reputable place.

Not to mention, you get to tour Eastern Europe! It's like a planned vacation with well planned meet and greets and pre-screened real women, many who speak English or they have interpreters. If I ever was serious about meeting a foreign woman, this is where I'd go first.
