Hi, I'm an educated artist with a love for illustration, especially for children. I am actually now working on a project for children book app, I could send You a sample to see, but I am also inviting You to check out my portfolio on Freelancer https://www.freelancer.com/u/passion4creation.html
I might be just the right person for this project. Hope we'll work together!
P.S. - I've put a bit long time frame because I'm currently working on two projects which we'll be done in approx.10 days... And, also since I don't know how complicated is the design You require for this...
