Inquiry about Custom Two-Seater Inflatable Couch

I am looking for a custom two-seater inflatable couch with specific features. It must self-inflate using a built-in rechargeable battery-powered pump, comfortably fit two adults, and use a durable lightweight outer material such as nylon. The base should be reinforced for surfaces like sand, grass, and hot concrete, and the product needs to be compact and portable when deflated, including a carry bag or strap. It should be water-resistant and UV-resistant for outdoor use, with a premium and stable feel, requiring attention to internal structure or support design. I need information on your experience with built-in pumps and battery integration, ability to support full custom design and prototyping (OEM/ODM), estimated MOQ, unit pricing, prototype costs, certifications for electronics and battery safety for export to Australia, and typical production and lead times.
