Parcel Locker Design for Sheet Metal Production

Hi,
I'm looking for a freelancer who can create a complete, production-ready sheet metal design for a parcel locker / smart locker cabinet.
The construction will mainly be made from 0.8 mm sheet metal, laser cut and bent. I have access to an Amada press brake (V8 tooling, approx. R0.6) and a Salvagnini P2 panel bender, so the design should be suitable for real manufacturing on this type of equipment.
I need more than just a 3D model or visualization. I need a complete manufacturing design including:
3D assembly model,
individual sheet metal parts,
correct flat patterns,
DXF files ready for laser cutting,
bending lines and bending dimensions,
technical drawings with dimensions,
assembly drawings,
exploded view,
hole locations and fastener details.
I would like to minimize welding as much as possible. Most connections should use rivets, rivet nuts, tabs/slots or other mechanical connections, preferably hidden inside the construction so that the outside surfaces remain clean and aesthetically pleasing.
I already have a concept/reference showing roughly what I want the finished product to look like, and I can provide pictures and dimensions.
The most important thing for me is that the final files are actually ready for production, not only a conceptual CAD model.
Could you please let me know:
Have you designed similar sheet-metal enclosures, cabinets, lockers or vending machines before?
Which CAD software do you use?
Can you provide STEP + DXF + PDF manufacturing drawings?
What would be the approximate price and lead time for a project like this?
If possible, please also send me examples of similar sheet-metal projects you have completed.
Thank you, Mateusz
