How to buy the lda city plot files?

I just saw the news that zameen.Com now has the exclusive rights to sell plot files for lda city phase 1 (jinnah sector). So how does it work? Whom do i contact to buy these files?

I suggest you to buy the plot on map which was balloted on 30 Nov rather then buying these files … Try to buy in Sector C on Map plot
