One way, as rajelectroniks have mentioned is to list with International Visibility by adding International Shipping. However, that will cost more and the buyers outside India aren't comfortable paying via PaisaPay.
A better option is to list directly on ebay.com. For this, you need to have a verified PayPal account which is very simple.
1. http://www.paypal.com
2. register
3. Add your credit card details
4. Wait for the credit card statement
5. Enter the 4 digit code from the statement to PayPal site verification page
6. Code matches = account verified. You can use this PayPal email ID to receive payments from International Buyers.
