Bath toy organizer design

Our company is selling bath toys on Amazon and we were thinking about designing a new bath toy organizer line that will be a similar style to these products with a unique eye-catching playful design (possible an animal shape as the second example):

One of our new product design projects is to make a new shape for this product:

https://www.amazon.com/Skip-Hop-Storage-Stowaway-Bucket/dp/B09M96NXCD/

Please let me know what will be the price for designing a product this way.

Thank you,
