Retro Console Prototype Build

Turnkey Hardware Prototyping: 1 Working Retro Handheld LCD Console (HTML5 Game Integration)

Project Description:

Overview:
I am looking for an experienced Electronics Engineer or Product Development Agency to deliver a turnkey (end-to-end) solution for a retro-style handheld gaming console. I need 1 fully functional, assembled physical prototype delivered to my address for evaluation and testing.
The console’s aesthetic and gameplay behavior are strictly inspired by the classic 1980s Nintendo Game & Watch systems (fixed-position liquid crystal movement style, but modernized).
What I will provide:
• The complete game logic and assets already developed in HTML5 / JavaScript.
• Complete high-resolution 3D graphic renders of the console's front and back design (Golden metallic premium finish, horizontal shape, specific button layout, battery compartment, and rear technical label).
The Scope of Work includes:
1. Firmware & Software Engineering: Port/adapt the HTML5 game logic into a light firmware (recommended for ESP32, STM32, or a similar budget-friendly micro-controller) to drive an off-the-shelf color TFT/LCD screen (2.4" to 2.8").
2. PCB Design & Hardware Architecture: Complete schematic layout, Gerber files generation, and Bill of Materials (BOM) sourcing. The system will feature physical buttons (UP, DOWN, LAUNCH, CATCH), a small internal speaker/buzzer for electronic retro sound effects, and must run on 2x AAA batteries as shown in our design.
3. Enclosure Mechanical Engineering (CAD): Design the physical enclosure around the internal electronics in a ready-for-manufacturing format (.STEP / .IGS).
4. Manufacturing & Assembly (1 Unit): Source the internal components, manufacture the PCB, and create one physical premium enclosure. For this single validation unit, the enclosure must be produced using High-Definition SLA Resin printing with professional metallic gold paint/lacquer, or CNC Aluminum machining. All text and rear label elements must be cleanly UV printed or laser engraved onto the body.
5. Final Testing: Deliver 1 fully functional, enclosed, scratch-free console ready to play.
Requirements:
• Must be a single engineer or agency managing the entire lifecycle (from digital files to physical shipping). Do not bid if you only deliver CAD or PCB layouts.
• Proven portfolio showing physical, assembled hardware prototypes (especially handheld devices or micro-controller projects with screens).
• Excellent communication and willingness to assist in component sourcing selection.
Screening Questions:
1. Can you handle the whole lifecycle (PCB + firmware + enclosure printing/machining + final assembly) and ship 1 working unit to my door?
2. What micro-controller and screen size do you recommend for this specific Game & Watch style project?
3. Please share a picture or case study of a physical, working handheld device with a screen that you or your agency have built in the past.
