Good Day Mr. Ahsan,
The businesses that i can recommend you in investing in Pakistan is the Forex trading and the business of cars. You can either invest your money in Forex as it is one of the really quick way to earn profit in case you find a good trader or either you can try to find a customer in Pakistan who's looking to buy a vehicle and import one for him from the Japan. You can earn good profits on big cars. If you still require several details contact me as i'll be really glad to help you with it.
