Review and optimise solidworks design for injection molding

We would like the successful freelancer to review our current solidworks design files and remove steps and other small errors in the file that make it currently unsuitable for production via injection molding. The model is almost complete and we expect for someone who has experience this will be straightforward. However if you have a flair for design we are happy to have you suggest small modifications that will improve the industrial design/appearance. You will need to ensure the parts fit together correctly in the assembled model and optimise any design features that make the current design not good enough for successful injection molding such as thickness of material used, steps, tabs and other legacy design. The design is for a small hand held plastic light approximately 25cm x 10cm x 15cm. We will supply the individual .SLDPRT files and the assembled file to the successful bidder. There will be 4 milestones 1. Review current design and report on your suggested changes required for approval by us 2. Delivery of 1st draft for review by us for any final changes 3. Delivery of final draft for review by us and any small revisions 4. Delivery of finished product including solidworks files and export into IGS and STL
