Hi,
I'm a children writer, and, what's more important, I am published and very creative=)
At the moment, for example, I'm working on the educational project for kids of different age groups. The aim of the project - to write a short picture story educating one specific theme in the foreign language (like "Animals") - so the language is a little scarce. You can see the examples in the private message (only short parts though, I can send the full texts on demand)...
(parts of the stories for 4-7 and 8-10 age groups.
About timings, o make everything perfect I usually make one-two revisions with you (or the editor) . The standard procedure I personally prefer is: I write the first variant, you look through - make comments and I re-write some parts within a day.
About cost and delivery date- well, I've put a bid for the whole story of 15K words and I think we will have a finished story within a month.
Thanks for reading,
Polina
