Can you guide me where this services are being offered? Thank you.
This is a starting point:
https://bitcointalksearch.org/topic/bitcointalk-escrows-trade-safely-855778
But basically, a green trusted hero or legendary member that hasn't changed his email or password, hasn't got "real" negative feedbacks and can sign a message with an old, staked address *MIGHT* be a good escrow... It might be wise to ask for advice if you don't trust somebody that is offering his escrow services tough!
If you sell some digital files, you can use selly.gg, it does quite a good job
The OP isn't asking about an online platform to sell code, he's asking on how to find and use escrows.
