Scriptwriting for a spanish wildlife documentary on . Only native UK English speakers

Kind of writing: Story
Num. of words: 500
Topic: Natural History - Spanish nature
Tone: Informal/Casual
Extensive research needed: yes
Extra notes: This proposal is to make six treatments from six different documents on 500 words approximately each one for a TV Series.

I would choose three different writers that would write two documents each (of 500 words each doc). I would be willing to pay £20 when the first document gets written and if I am happy with it I would be happy to pay £40 for the second one making a total of £60 for both documents if the freelancer is good on the first one.

This job would entail researching on the Natural History of the Iberian Peninsula and some animals from Spain establishing first the most remarkable location where they are found and describing later interesting facts and stories that would come from the research on each animal (no people related stories).

Once the seller has written the document he/she must be ready and happy to correct it adding or modifying it according to my guidelines until I am confortable with the final job.

If you were to apply for this job please let me know what would be your preference and why you think the Iberian Peninsula is a remarkable place for wildlife within Europe.

Thanks
