Hello there,
I have read the description. For the first category, my understanding is that I must train you to model components (similar to that in the attached pdf) quickly. As for the second category, you would be designing an engineering product and I will be supporting you for it.
I am good at 3D modelling, theoretical calculations and manufacturing techniques. As for simulation, I do not have a software for that. So I am quoting only 100 USD as I cannot help for simulation and you might need to hire someone else for it.
I am undergrad mechanical engineer with 2 years of professional experience. I have been using Fusion 360 for about 4 years now. I am confident that I can deliver satisfactory results and am looking forward to working with you.
Best regards,
