Reach pindi or isb from daewoo which costs 520 rs per person, then rent a car, any type car which prefer, a Mehran taxi will cost you about 25-30 thousand rupees for three days which includes fuel also and he will take you around to every main attraction of your tour, and will also take you back to Pindi also, from there you can again catch a daewoo back to gujranwala, if you want more budget friendly tour, then take a natco from pindi, and don't ever take any other local transport in these areas, there are many hiaces going in cheap rates, don't get trapped, they are so unreliable, many accidents happen with these types of vehicles, if you can't afford then don't go but please don't risk your lives in these kinda vehicles. Best of luck for your trip.
