Well, it's hard to compete with a Bitcoin Casino. We're also offering a 2%+ credit towards people that trade with us. Also let's remember: not everything is about money.
Maybe, but would you take the exact same job if an offer came in but it paid you less?
If you have limited funds and want a respected members maybe offer 2-3 respected members to buy their signature spaces. Instead of making a signature campaign just employ some people to permanently post for you.
You could try this, but without significantly changing your terms in several ways I doubt you'll get anyone signing up to this.
