I’m seeking a complete development solution for a consumer electronic product, specifically an electric heating unit for shisha that uses controlled heating functionality instead of charcoal

I’m seeking a complete development solution for a consumer electronic product designed specifically for controlled heating.
This product is intended for use as a modern alternative to traditional charcoal in hookahs/shishas. The heating should be even, safe, and user-adjustable to mimic charcoal heat without burning tobacco.

Key Requirements:
• Controlled heating functionality with adjustable temperature.
• No smart connectivity, no Wi-Fi/Bluetooth, no recording.
• Compact and safe design suitable for consumer use (home environment).
• Simple interface (one or two buttons, LED indicator if needed).
• Power through wall outlet (AC) or rechargeable battery (optional).

Ideal Skills and Experience:
• Experience in heating element design and control circuits.
• Strong background in consumer electronics development.
• Familiarity with safety standards for heating devices.
• Ability to provide working prototype and support mass production later.
• Portfolio of similar heating or compact appliance products.

Please include your previous work and estimated development timeline.
