You're not being too cooperative about your issue, nobody will help unless you try to help yourself more.
Good If you're doing "white hat" SEO, it's going to take some time to start seeing good results (depending on how competitive the keywords are). Try targeting less competitive keywords. You can check this by using Google Webmaster Tools Good Check your keyword density fro each article and make sure it's between 1-3%. having a keyword density that's too high will make it look like you're keyword stuffing.
Explain your problem in details and seriously like you are in trouble. Dont expect that you invest so less time to explain your problem by stating in hurry, and others will invest their valuable time to solve your problem.
