How long will it take you to finish the job?
10 days for all the design, excluding feedwork and changes.
Proposal:
I believe I'm very creative. I can provide you the product as per your detail, because I'm a mechanical engineer, and I operate of Solidworks and Ansys only. There are lots of consideration needed to be done while formulating plan, planning and developing the product, where implementation include design parameters, like units, BIS, ANSI etc. you please provide me details of design of model in what units, secondly, I have to consider solid modeling attributes like stress, strain, material requirement, etc,
With your weight limit, I guess the equipment would be of plastic material, so plastic modeling have to be done.
And I'm the best, because I am design engineer by profession and choice. I can do your work, I'm new so can give you concessions, 50% discount.
Thanks
