You'll probably have to end up going first since you're not vouched. Also, if I were you, I would trade with reputable members in the beginning to minimize the risk of scams. In the beginning, you may have to sell some of your items for a price lower than what you would expect to get if you really want to get those vouches fast.
I don't know about the rest, I'm not an RWTer.
Good luck on your selling.
