Inquiry about Children's Audio Storytelling Device

I am looking to purchase a high-quality children's audio storytelling device for retail sale in Australia. The target age group is 3-8 years. The device must be screen-free, durable, child-safe, with a rechargeable battery (USB-C preferred), simple navigation for children, and support story cards.  
Please advise the minimum order quantity (MOQ), unit price (FOB and CIF Australia), sample cost and lead time, custom branding options for logo, packaging, and voice content, existing certifications like CE and RoHS, and production lead time after order confirmation. Compliance with Australian toy safety and electrical standards is essential.
