You're so demanding about the pay rate, $18/week is so high for your account. Even DT 2 users which also campaign managers who made the SMAS have complaints about you're spamming in this forum, so I don't really think that $18/week is so worth it.
I'm also with @dodgrad, much better if you follow what he said.

Because you have negative trust, can you consider lower rate per week? I would like to start from BID = $1/week.
