I have no idea what it is that you want to have written or how many words are needed or whether conciseness and precision are part of your prerequisites. But vagueness should be no obstacle and as in the days of yore, I will throw my hat in the ring at the jousting match and see what bell sounds. I can make up stories at the drop of that hat or any other hat for that matter and though they will not necessarily be up to the standards of the Mad Hatter in Alice's Adventures in Wonderland, they may come back down to Earth like Charlton Heston in Planet of the Apes.
On the other hand, if your content requirements require being able to write out random things stretched along a thought line into a coherent turn of phrase, then I can do that, too.
If your material is serious, then naturally I will also be. Subjects dealing with Earth Science and subsidiary branches are especially welcome since I tend to keep myself up with the latest in different fields just because that's what I do in my spare time.
So let me know, eh?!
