Hi there,
I saw your call for an illustrator and I would like to express my interest to learn more about your project and hopefully discuss terms of cooperation. I'm a traditionally educated artist, working as an old-school illustrator for many years, lately mostly on children's books. Being a traditional artist, I can offer pencil, pen and ink, coloured pencil, watercolours and gouache, or a mixed medium. I normally deliver high resolution scans, but I sometimes also send the originals upon request. As you say you are looking for something simple, my quote is a flat rate for entire illustration package and includes characters design, 13 one page colour illustrations, illustrated end pages, some spot illustrations and cover art.
Few samples of my commissioned work are available at https://www.freelancer.com/u/ddimitrovska.html, but I would happily send more samples if you are interested. Needless to say, I'm available to discuss details over chat and I'm looking forward to hearing from you,
best,
Dusica
