Women's ring 3D design and wax moulds

I want to make an exact copy of the atached picture of a women ring. I have further criteria like the maximum weight of the Gold ring (not to exceed 6g). more details will be provided. On the attached picture I only wanted the ring to be designed and made as a wax mould ready for casting.

please note that if I like your services, this will be a long term bussiness relationship that could involve designing hundreds of jewellery products.

Thank you
