Cold Calling to Russia and surrounding countries to sell London flats

I am looking for someone who speaks fluent Russian (Native) and has lived in ex Soviet Union countries so has experience of dealing with the people. The goal would be to cold call and call estate agents in ex Soviet Union countries (Russia, Tajikistan, Uzbekistan...) to propose to them to buy luxury refurbished flats in central London. Previous Real Estate experience a plus but not a must.
