It is good that you are open to using an escrow. However, I think that the main problem of your
offer is something different:
...
You require that a potential buyer sends you proof of ID. This is obviously understandable, because
you want to protect yourself against people with nefarious intentions. Nonetheless, your account
has been registered today and you have no reputation in this forum at all. People obviously are
highly hesitant to send a scan or a picture of their ID to someone unknown, because they would open
themselves up to all the shenanigans that can be done using the ID of someone else (identity theft).
If you want to trade using SEPA I would simply suggest signing up for one of the exchanges
with SEPA bank transfers like Kraken or Bitstamp (my recommendation).
