I'm selling some coins on LocalBitcoins in low denominations and have worked with one person who sent cash in the mail rather than meeting locally.  To be honest, I'm surprised they trusted me enough to do that when I had no reputation on the site, and so in an attempt to reciprocate that trust, I film myself opening the envelope and counting the cash just to be on the absolute safe side.  That said though, I would probably also accept a money order, or even a personal check as long as I'm allowed time to let it clear before releasing the coins, but again I'm dealing with less than $100 per transaction.

I truly hope your $560 transaction works out well.  When you're dealing with a currency in which transactions are irreversible, a healthy dose of paranoia and caution is always warranted.
