Articles writing for blog posting

Hi, I am looking for someone to write 30 articles for me about children's educational toys (0-12 years old). The content is for a blog posting. Articles should provide useful info to catch reader interests. The topics should be appealing to the target customers (parents, mothers, grandparents, etc). Each article should contain around 500 words of ORIGINAL UNIQUE CONTENT. No illegal use of copyright material. No copy and paste. Please indicate the estimated time it would take you to complete the articles. If you do a great job, more planned work will come your way. The first 10 articles should be totally unique, the rest of 20 articles can be spun from the first 10 articles, but the spun versions must be over 50% unique. I will provide a website where you can find educational toys to write about (if needed). Thank you
