Inquiry about Custom Collector Car Model Manufacturing NEW

I am looking for a manufacturer to produce a limited-edition collector car model based on my own vehicle design. Specifications for the first model: - Scale: 1:20 - Quantity: 50 pieces - Highly detailed collector quality with accurate exterior proportions, high-quality paint finish, detailed wheels/tyres/brakes/badges, and a fully detailed modern interior - Clear separate light lenses instead of painted lights, fine exterior trim, and photo-etched parts where appropriate - Numbered limited edition (01/50 to 50/50) with a black display plinth and clear acrylic display cover An optional lighting system is also of interest, including working LED headlights, rear lights, dashboard illumination, and a concealed battery/switch. The model does not require opening doors, bonnet or boot; the priority is extremely accurate appearance and fine detailing. I can supply reference images showing all design details. Please provide information on your recommended manufacturing method, prototype process, tooling requirements, production timescale, and approximate costs for this 50-piece first edition. Further limited‑edition models will follow if quality is excellent.
