Where are you located such as country.
If you are in Europe I don't think bank transfer will work outside of there or if they do will take a long time to clear.
Not worth it to me if you are waiting for along time for the money to be received after sending the btc.
No one will trust a newbie unless he goes first. When we see the money in our bank account, we will release btc. You are right. If the transfer fees are too much, no one will do it, including op.
