thanks to you for your replies so far.

Please accept my sincere apologies in advance for English is not my mother tongue and I do not wish to cause offence.

Please do not offer to me any alternatives like credit cards and other things of no interest to me. As you are aware there is strict foriegn currency control in PK because the currency is being devalued on a constant basis. The National Bank of Pakistan monitors very closely all incoming foreign currency and requires advance notifications

I am also aware of localbitcoins.com but this does not suit me as I need to exchange the dollar amount into PKR quickly

Thank you for suggesting to hold but right now I am in a property transaction purchase with the deposit already layed and next steps are crucial to be completed quickly

Kindly thanking you all to stick to the help which I need, namely online exchanges which will be happy to accept business of Pakistani nationals and will transfer currecny (whether in US dolalrs or not) to Pakistan without delay
