3D Design of Electronics Casing

I am loooking for someone to 3d model a plastic casing to suit an electronics board that we intend to get plastic injetion moulded, this model does not need to be 100% "working" model, just a visual representation of our design ideas that we can present to the injection moulders to proceed from there. Requirements: The casing will be made up of 3 parts 1 part to be a hollow box (similar to extruded aluminium), with 2 of the ends open in order for the circuit board to slide inside (approx 10cm x 8cmx3cm). This part of the case will need to also have our logo sunken into the top, and include 4x mounting legs, as well as have a method to allow the end plates to attach without use of any screws (clip lugs) 2 parts to be a "end plate" we can clip over each end of the hollow box, to seal circuitry inside the box. Overall we are looking for a visually appealing design that incorporates our logo, 4x mounting legs for attaching the case and some smaller design features to make the casing unique and attractive to our clients,
