CAD drawing of offshore engineering - (jack-up drill-rig design)

I’m looking for a UK-based freelance AutoCAD draftsperson with offshore or heavy structural background to assist with a conceptual jack-up drill-rig project.
This is early-stage development — clean GA-style visuals and simple 3D modelling from supplied engineering sketches. No fabrication detailing, no class packages, and no calculations required.
Ideal profile would be someone with prior offshore, fabrication yard, or heavy marine drafting experience who enjoys turning rough ideas into credible engineering visuals.
Remote working is fine. I’d prefer to start with a small paid trial task and develop the collaboration from there. I would suggest an initial (Paid) trial to commence and then we can progress from there..... For instance convert the pictures/sketches i have uploaded into a upgraded visual... not 3d, just 'better visually' i would like the 'sketch' converted into a diagram like split-tube leg, using split tube leg (Red) as a reference... please.
