Which kind of payments do you recieve ?
If you want, I can recieve on your behalf and you will get the payments in PK. I am based in Canada and I get funds from Pk for my studies. It can work. But you would have to tell me source of the payment because Paypal has got strict rules. Also I got paypal shopping cart. You will get the payments in your SC account. Since I can send from here. I Will charge you the current exchange rate + 5% in both cases if payment is less than 1000$ . For above 1000$ Amount can be submitted to any bank in Pk. Exchange Rate + Bank Deposit Charges would be charged. Exchange Rate would be the Rate of SC Bank or any bank in Pk which I can see online. Rate at the time of sending you the money would apply. Secondly, If you want to send money, you can send to my account . It will cost you 15 $ on top of the amount you send. You will have to send the amount in USD, so USD - CDN conversion would also be charged. It would be the rate that Paypal Automatically sets.
P.S If by any chance, I Am voilating the rule of this forum, Please Delete this post. I am just doing it to help the Pakistanis since I knew the issues I was facing once I was in PK
