Web UI Design and Illustration for Online Preschool

My website shall be multi-page platform for delivery of online preschool curriculum. Need design and illustration for:
- landing page (before subscription);
- home page (after subscription);
- online book reading;
- online songs;
- online puzzles;
- online colouring;
- online games; etc.

All illustrations have to be original, not collected, to avoid duplication with other works as well as consistency within my site. Interactive, clean, tasteful, and innovative works are expected. Files are to be provided in psd format in layers for different components.

For convenience of understanding, please see some similar website links below:
