Take a sketchup drawing of a trailer chassis, and make into production drawings

I have designed a flat deck trailer concept and need an experienced mechanical CAD designer to convert it into a complete production-ready CAD model and manufacturing drawings. The end result should be suitable for fabrication, laser cutting, and manufacturing. Trailer Overview Sub Chassis 75 × 50 × 3 mm RHS chassis rails Pre-drilled for mounting beams A-frame drawbar Flat Deck Overall deck size: 2000 mm (W) × 2800 mm (L) 65 × 35 × 3 mm RHS main frame 40 × 40 × 3 mm RHS subfloor structure 25 × 25 × 2 mm tie-down rails 25 × 25 × 3 mm angle for decking mounts 50 × 50 × 4 mm corner sockets for removable ladder racks Mudguard mounting brackets Underbody toolbox mounting brackets Hardware 250 mm high drop-down tailgates on all four sides Removable front and rear ladder racks Scope of Work The successful freelancer will: Produce a complete 3D CAD model of the trailer. Ensure the design is practical and suitable for fabrication. Create all manufacturing drawings. Produce laser cutting files where appropriate. Create weldment drawings and assembly drawings. Generate a complete bill of materials (BOM). Include dimensions, tolerances, hole locations, and material specifications. Suggest improvements where appropriate to simplify manufacturing or reduce cost. Deliverables Native CAD files (preferably SolidWorks, Autodesk Inventor, or Fusion 360) STEP file PDF fabrication drawings DXF files for all laser-cut components Assembly drawings BOM with material sizes and quantities Ideal Candidate I'm looking for someone with experience designing: Trailer chassis Steel fabrications Weldments Off-road or automotive products Production-ready manufacturing drawings Experience designing products for CNC laser cutting and fabrication shops is highly desirable. Please Include in Your Proposal Examples of similar trailer, chassis, or steel fabrication projects. Which CAD software you use. Estimated timeframe. Fixed-price quote. Any recommendations you have for improving the design before modelling begins. I already have a clear concept and basic dimensions. I'll provide sketches, measurements, and answer any questions required during the design process.
