As'salamu alaikum
I'm currently a student, hoping to assemble a database of all the car part suppliers in Karachi (and prolly Lahore) so that people and businesses (like workshops) in other less developed cities can access the contacts for those suppliers. The database would not only list them, but it'd also rate and review them through public on-ground reviews. Trying to solve problems for businesses that have to get marketed products through retailers, with limited local options to choose from.
Any help in understanding the supplier situation or dynamic in Karachi (preferred) and Lahore would be appreciated, and also any tips on how I can contact all of these quality suppliers.
Jazak'Allahu khayr
