Money for inviting family to our wedding

My Ukrainian fiancee and I want to get married in October 2015. Unfortunately her parents and family do not have enough money to pay for flight tickets. The reason is the Russian invasion into Ukraine and the resulting economic difficulties. We really would like to celebrate the most important day in our lifes with all our whole family and friends and so we would be extremely grateful for any donation and support we could get. Thanks a lot and god bless you.
