Yes you can.
I talked to one rent a car driver who I hired from Mingora to Miandam.
He quoted Rs. 6000/- for a two day trip from Mingora to Kalam and back. From Kalam you will need to hire a 4 -Wheel Drive Jeep to go to Mahudand, which will cost a further Rs.3500. These prices include fuel also.
If your a group, then the amount can be shared. It is the best option.
