On any international sale, do not do paypal. Bank to bank wire transfer is the best, safest and safest. Shipping should be via ups, with signature. However, there may be duty and VAT issues that could cost you about 25% of the value of the goods. If the buyer does not pay the latter costs, UPS's brokerage arm will look to you for those amounts. So price the sale accordingly.
