Jewellery technical illustration

We are a new jewellery brand, looking for some technical drawings to illustrate the removal and insertion of an interchangeable signet within a ring band setting.

I'll be able to provide some images of the mechanism and steps we need to illustrate, along with a sample product to refer to.

There will be approx 4 distinct images. I anticipate they will be primarily line drawings, but we'd like some personality added - maybe some flashes of colour.

Happy to arrange a price per hour, or a fixed job rate.
