Just to let you know your feedback is horrible. You don't even sound like a native english speaker because you make no sense when attempting to convey your needs. You have to be much more specific on what you're looking for. Your initial post says to make it vectorized and cleaned up professionally, just about every poster above this one has done that for you then you go telling people its not what you're looking for. Count me out of this one, so tired of people who don't know what they want and expect others to read who knows who's mind...
For the people, no i'm not a native english speaker. @Focus: You are still close, like the text, can you use the text, of your latest logo. And then lift out the text from the logo, and use the colours, black/yellow/red for the letters. And then shape under it or above the text. When you don't get it, then please say it. For example: You see the text, and the logo.
Final shape was: (one of 4 variants) Files sent, payment recieved, Itrader added. Thanks for mysterious, interesting contest.
