bhaijaan my brotherly advise is that if u can invest 1million pak rupees then go to sharjah scrap market of cars and buy branded 14,15,16inches with 4 bolts and 5 bolts pattern brands like BBS, VOLK, OZ, enkei must be branded stuff, buy that lot make sure any repairs and ask the same scrap yard market to clear the goods and deliver it to karachi via Gawadar on lum sum fixed amount and sell those rims via internet making your own company website or u can pay 8,000 per month on pw for non-sticky topic, or u can make several ids as most of the people have on pw to sell rims etc. i will assure you, u will get good response as u can see people buy branded rims which are taken off from a half cut vehicles or from torkham border and sell on pw more than the prize of new ones.
take care
