I need a driver/translator in Karachi

Salaam, I am visiting Karachi, Pakistan with family for a shaadi and need a tour guide to take me around town and help me get some personal supplies (SIM card, power adapter, salwar kameez, etc), and I would also like to explore the underground scene. I would like to speak to addicts to understand the kinds of substances they use, how much they are spending on them, and where they are getting them from, and I would also like to speak to sellers to understand how they are treated by police. I might also want to speak to some poor people to get to know how they live their lives. This project should take no more than 3 working days in total. Ideal candidate would have his own car (or be able to arrange for one at his own expense), a long history on Freelancer, knowledge of Pakistan’s drug scene, and be cool with pretty much anything that might pop up along the way.
