Do some Blog Posting

Hi, I have a software program that allows teachers to create on-line quizzes, tests and assessments. It's available at www . questbase . com. I also have a facebook page at [login to view URL] and a blog at [login to view URL] In order to draw attention to my blog and facebook page, I'd like to post some articles about tests and assessments in general. I'll post technical articles myself (new updates, etc.) but I'd like to have someone that can write a few general articles about the topic of my program (tests, assessments, grading, ...). For example, the first article I'd like to post is something like "Best practices to create multiple choice questions". It's plenty of similar articles in Google, so it should be an easy task. I'd like to split the article into 3 parts, so that I can post each part separately, for example once a week. The writer must be VERY fluent in English (preferebly mother-tongue). The first article is about this topic, but I'd like the writer can suggest other topics for the future. For the first article, I prefer to receive it and I'll post it myself to my blog; for future articles (once I know the writer), I'll give him/her the password to my blog (created in Blogger) so that he/she can directly post articles: I'll just approve them before being posted. I don't like blog articles only with text, so maybe 1 or 2 images (if applicable) in the article are welcome. I need to receive some past articles already written by the writer, to evaluate them. Is the writer is good, this project may become an on-going project, for the following months (I always need articles).
