Al,
The easiest way to get paid is if he has a credit card that you take. That way you nor he has to convert money. If he doesn't have a credit card, then the next best thing is a certified bank check from an American Bank.
If you use Paypal, you might get burned, because I don't believe that they secure funds. If they do, then that might be another avenue.
Another option might be electronic funds transfer from his account to yours. This would need to be done through his bank and yours.
As for shipping, Global Express US mail, will get it to his country in 3 days, for around 25.00 - 30.00. Surface will take 30 days but will be about 7.00. After it gets to his country, who knows. You will also find out about customs forms. Part of the form will ask contents and value. Depending on country he might have to pay import taxes. Also, some countries prohibit knives of certain designs, i.e. double edge of any style, not just daggers, Automatic openers, gravity knives, assisted openers.
Good luck. I know it's alot of headache. But you know what a satisfied customer is worth.
