I recommend Huntington T. Block Insurance in Washington, D.C.  They deal mostly
with arts and history institutions across North America. Many major museums use
them because they are very cost efficient. Call Lynn Marcin at 800-424-8830. She
is the Artsure Representative for The American Federation of Arts.  She is very
efficient and reliable.  Tell her that I referred you.  Good Luck!   Let me know
how it goes.
