Dear Sir,
I am a mechanical engineer with experience in product design. Proficient in 3D CAD, I have done folded metal sheet, thermoplastic and mechanized parts for short series products.
I plan to address your request spending 15 days with preliminary designs, until we reach an agreement on an appealing one, and then in the course of next 15 days I will prepare the production design for the prototype.
In the process I would need to know some extra information to guide the design: intended qty, manufacturing facilities available, security standards to address, etc.
Best regards
