Hi there,
I just saw your call for illustrators and I would like to discuss your projects. I'm an experienced old-school children's books illustrator, so please take a look at https://www.freelancer.com/u/ddimitrovska. The quote is what I approximately charge for a one page full bleed full colour handcrafted illustration when more than 10 illustrations are commissioned. Rates are, however, negotiable and depend on the style, level of detail, format and urgency.
I'm available to chat and I'd be happy to hear from you,
kind regards,
Dusica
