Me and my partner want to engage in a sequence of Bitcoin transactions. The first transaction involves me sending $400 in BTC, and the second transaction involves my partner sending me $900 in BTC. To establish trust, both of us are willing to deposit $900 in BTC into an account, which will be returned to us after the completion of the transactions.
How should we proceed? How do we find a trusted intermediary?

Using a trusted third party as an intermediary is just going to add extra cost to the value of your transaction which is a loss that can be saved if you can make a trustworthy trade partner and engage in dealing with him.
