Children's Bedtime Stories

I am contemplating a project for which I will need a very creative writer who can write a variety of short bedtime stories for children ages 4-8. Each story will be 800-1000 words in length and will be based around positive character traits (ie., courage, friendship, honesty, etc.). I would like to eventually publish a series of children books – one book for each character trait – with anywhere from 20-30 stories per book. At this time, I am trying to find a creative writer(s) that impresses me as someone who could help me with this project over the long term. If you have writing samples that you can send me, this would be ideal, however, I am willing to pay a few writers to submit original stories on any of the above-mentioned topics. If you would like to submit a story, I can pay $35 per submission if I feel you have the capabilities to write compelling short stories for the age range indicated (4-8 years). Please submit any information about your creative writing skills in this regard. If I haven't been clear, please do not hesitate to ask any questions. This project is in it's very initial stage, so my explanation may still be somewhat disjointed. Thank you.
