I am really not sure how the community will react on this thread since I am not near to a legendary or above, not very long with this community and never worked as an escrow before
I think you're nuts

Considering the high amount, and the long duration of the escrow, you may want to consider a 2-out-of-3 multisig: OP holds 1 key, and 2 escrows each hold one too. That way, 2 out of 3 parties can always make a transaction.
