Draw a new ergonomic handle for an existing handle design

Requirements

1. To draw/design an ergonomic handle grip for an existing handle design. I have a sample of the grip and I would like the dimensions of this sample grip to used.

2. To create 2D Technical Drawing with exactly the same content details as the sample 2D technical drawing attached below, with the bolt extending out and showing the internal mechanics of the handle, but showing the new ergonomic handle. This version will eventually be used for plastic injection moulding.
3. To provide 3D CADs in stl. and step file formats of the above.

4. To draw 3D CAD in stl. file format, of new handle but this time with a hexagonal hole. This version will be used for 3D Printing so the bolt will be inserted after printing. (See attached stl file for details).

I have the grip I want used so it would be far easier for us to meet up for 10 minutes in town so I can give you the sample and discuss what I want. You can take the sample to work with, but I will need it back. I'm working in Ladbroke Grove this week, so if it's convenient, I'd like to meet there.

Please submit a price for the work if interested.

Thank you
