@mikmech - establish your station / service centre in Rawalpindi around GT road, towards Peshawer outside cantonment limits, in times to come Islamabad will be like fort with certain curfew like timings for selected areas. You will suffer for IDLE time (zero productivity)
Rawalpindi outside cantonment limits will remain accessible by either side of town & residents of Islamabad. The service quality & credibility of your commitments will bring people from around.
