Need a review to get the illustration services

Hello everyone, This is Margaret Smith, and I like art illustration designs, and I have used several projects, but I'm not satisfied with their work. I'm here to get help from you guys about a new platform that I found, now named Children Illustration. I want a service of childrens illustration magazine illustration from them. Please let me know if anyone has an idea about this company and whether their services are good or not. Thank you.
