although the matter to be designed is not clear, I would work my best to design the 3D logo as per your requirements that too within the specified time.
Relevant Skills and Experience
though it would be my 1st project as a freelancer, I have studied as a manual Jewellery Designer and a CAD designer so it might be easier for me for draft a concept and then work on the 3D model
Stay tuned, I'm still working on this proposal.
