Creative fundraising writer

We are a Registered Charity and we require an exceptionally talented creative writer to produce a heart provoking letter to our mailing list to seek urgent funding for a 63 year old Holocaust survivor whose entire family perished in WWII and is now in desperate need of medical treatment for various ailments. His health is extremely poor and he lives alone. He suffers from severe depression and has no one in the world to turn to and is relying on us to try to raise the money needed to restore him to health.
