My friend, I am just giving you a friendly advice:
a) People here are not stupid. Telling your friends (with 3-4 posts) to post here that they'll buy for you doesn't work. People are not so stupid here.
b) Take an example from people who were in your situation previously. None of them got serious interest because a) Their post count wasn't very big b) No iTrader c) No reputation. So free is the least you can offer considering your current situation.
Take care.
