People can only bid or you can do GIN as an option, but you are new, so they can only bid right now. So, if the highest bid is 1000, then you are supposed to honor that bid. The positive side is that it could go over 5000. Anyway, you take your chances. Eventually, you can set the start bid higher, but not yet.
Also, you might want to get more then one verification. It is easy to make a fake Facebook page. And if you keep shipping on there, especially at that price, you probably won't get much of a bid.
