Sorry guys, I was out of town so I miss this thread.
My experience as italian is: it's easy to get a paypal account, but you have a sending limit, (at least I have one, 2000 $, and it's not a monthly limit, it lasts forever!), because of VISA restriction, so you must have TWO different Credit Card, like Visa and Amex, to exceed this limit.
It's not possible to send send a IMO from Italy to US because the postal services of Italy and US don't have an agreement about that, it's crazy, but it's true!!.
You can send money via Western Union or Moneygram, but it's expensive, or via Bidpay, a little bit cheaper. My suggestion is that your customer open a paypal account with a credit card otherwise he could pay you via Bidpay with a credit card. Anyway if you have a "real big problem" with your customer, send me his mail, I will try my best to help you.
