Also if I have none made trades so far and and zero respect, how do I start building it up?
Try to us local payment like local bank or face to face for first. I use face to face method before so it will be more safe. After you got some reputation, you can try to accept another payment like paypal or something.
Since localbitcoin use escrow too, even your reputation is zero, some people maybe interest if you place buy at low price or sell at high price
