I need drawings for my fantasy novel - A place where I can request drawings free of charge?

I'm writing a fantasy/sci-fi novel and I'd like to have drawings of the characters to use as a visual aid. Do you know if there is a site that accepts requests to do drawings free of charge?

If you would like to do it or if you want more info, let me know. You can contact me in this question or via Y!A email message. Please do not say you will do it unless you can commit. There are only 4 drawings I need. One of each character. I don't really have a time when I need them done, but the sooner the better. One or two weeks would be awesome. It'd be cool if you could start right away.

And again, please do not ask for money. I do not make deals over the internet.

More Info:

This is not a medieval setting, but more of a post-apocalyptic setting, so the clothes would look not be fancy or colorful. The clothes should look modern but since it does not take place on earth they should still be different.

The people in the area where the story takes place have many Asian and Filipino features. They are not tall and do not have long arms and legs. They all have dark brown eyes and black hair. Their complexion is relatively dark.

As far as the style, I do not want anything too cute-looking or anything sexual. I鈥檓 pretty flexible as far as the drawing style. It doesn鈥檛 even need to be anime. Don鈥檛 try to make it look like a cartoon. I would rather have them look real.

If you want more info before committing, let me know.

Kinda like a facebook for artists. You can post an ad in the forum :)

So let's see, you want a skilled practitioner in a very narrow professional field to give up their time for you for free?

Get bloody real, man. It might surprise you to know that we artists actually WORK for a living!!!!!
