Compact Stainless Steel Sheet Metal System Design

I am looking for a mechanical designer to develop a compact stainless steel sheet metal system consisting of a base rail, adjustable clamps, several interchangeable modules, and a removable work surface.
I already have initial concepts and visual references. I need the design refined for prototype manufacturing using laser cutting, press brake bending, and welding where necessary. The intended sheet thickness is approximately 1.5–3 mm.
The design should provide straightforward assembly, adequate rigidity, standard fasteners, and modules that can be easily removed and repositioned.
Required deliverables:
Complete 3D assembly and individual part models in an editable native CAD format.
STEP files for the assembly and individual parts.
DWG manufacturing drawings and sheet metal flat patterns, including dimensions and the information required for cutting, bending, and assembly.
Assembly instructions with an exploded view and assembly sequence.
The specific application, dimensions, and visual references will be shared with the selected designer after agreeing on confidentiality. The design must not be published or shared without my permission. I require the rights to manufacture, sell, and further modify the design.
Please provide your price, estimated delivery time, CAD software used, and examples of similar projects. Please include one round of revisions following prototype testing in your quotation.
