Design a housing based on my 3D model

Hello, I'm looking for a CAD designer experienced in plastic and metal parts design. The job is to design a housing, composed of plastic and metal parts, for a small, simple electronic device. I have a design concept (outside view) designed using Blender 3D. This can be improved if you have some creative ideas, but the main goal of the job is to design all the mechanical details with manufacturing technology in mind. During the design process the design would have to be consulted with electronics designer. The final design would be approved by a housing manufacturer. The housing will be simple, a box of about 6cm x 4 cm x 1 cm, 3 small sockets, 1 pushbutton. We've made only a few housings in the past and each one is different, but I can share lessons learned from the previous designs, including source files of some details. We can also as a manufacturer for advice and recommendations before we begin. Deliverables - what I would like you to deliver. 1. Renders for approvals 2. Source files and related docs. 3. STEP files for electronics designer (or other format convenient for both parties). 4. Files for manufacturing (if different from 2.) 5. Intellectual property copyright for all what you deliver. Please feel free to ask any questions you might have. I will be glad to answer them.
