you are putting real money thats serious stuff, i'll tell you bluntly pakistan is a backward country not much investment prospects here and the safety of capital is very questionable, pakistani govt has the proven track record of rewarding individual successes by nationalizing their businesses, the pakistani govt has in the past seized dollar accounts in the name of national security which at the end was the biggest foriegn exchange scam in pakistan history. stock market is manipulated to the core, corruption is king, IF YOU INTENT TO MAKE MONEY THROUGH CORRUPT WAY PAKISTAN IS THE BEST PLACE.
there is nothing much here besides as the food as core entertainment for masses, eat out at restaurant then go to some other place for coffee etc may be eat ice cream thats it, so food business has some prospects and maybe buying real estate to sell it at higher price to some pakistani living abroad. thats all to it
lastly pakistanis who reside in pakistan have very limited horizon more like tunnel vision 'cause there is no infrastructure exist locally to broaden their horizon, you'll find patches of pakistani people like in this forum who may have higher general knowledge about things in the world due to knowledge gained through internet and thats about it. those who wants to better their lives are handicapped with as minor things as payment options from paypal as threads after threads show the desperation to overcome such a minor payment method locally in this day and age of commerce.
majority of big business are dominated by international and local family owned cartels, very monopolistic dominance leaves little room for entrepreneurship.
My suggestion would be to look internationally to invest money through mutual funds for starter. check out T Rowe Price Funds and Fidelity Investment Funds for starter. return could be 5% to 30% depending how you choose funds
