Custom Electric Pig Rotisserie

I’m opening a small food-service venue and want a purpose-built, electric, motor-driven rotisserie that can comfortably turn a whole pig up to 30 kg. The unit must be robust enough for daily commercial use yet compact enough to fit a professional kitchen workspace. Here’s what I’m expecting: • Engineering drawings (CAD or similar) that show dimensions, material gauges, motor specs, spit design, bearings and any heat-shielding. • A bill of materials specifying food-grade stainless steel or equivalent, NSF-compliant components and a reliable, quiet motor with speed control. • Fabrication and assembly of the finished rotisserie, fully wired and tested, ready to plug into a standard mains outlet (advise voltage/amp draw). • Clear instructions for cleaning, maintenance and safe operation, plus any certifications required for restaurant inspection in my region. The machine should run evenly without hotspots, keep grease contained, and be simple to load and unload a 30 kg carcass. If you already have proven designs or can prototype quickly, let me know your timeline and any questions so I can move this project forward.
