Really u r making good efforts on this,but I personally believe that one can sell it without a lawyer also,I m not sure how,but just try to talk to the developer directly and may be they have a set procedure we need to follow , ultimately they r still charging a fee of 2% for transferring. I sold one of my property to a friend ( whom I trust and he did trust on me ) and it was very smooth like a piece of cake.
Best Regards
