HI there,
I would like to express my interest in your projects, as it seems to me that you are looking for an illustrator that would deliver handcrafted illustrations. I'm a traditionally educated artist, and an experienced illustrator, lately working mostly on comics and children's books. You can see some of my recent commissioned work at https://www.freelancer.com/u/ddimitrovska.html. As for your conditions (1-3), you can rest assure that I will do most of the work independently and only request your input where you would insist of giving it, as well as that I would strictly follow the deadlines.
Additionally, I'm willing to provide a test sample prior to any agreement.
My bid is what I normally charge for around 20 detailed coloured illustrations, for purposes of orientation. However, I'm open to various kinds of arrangement, so the price is also open for discussion.
Hope to hear from you,
all the best
Dusica
