Seeking cofounders for jewelry line

This is nor primarily a tech startup, but incorporates an ecommerce component.
I already have a client base for related products and I'm looking to add to those a jewelry line for a specific niche. I'm looking primarily for a designer (ideally with jewelry or 3D design experience) and a marketer. Products will be sold both through retailers and online.
I can contribute with an already setup office, client base, some money, website and would take care of business development/sales. Like I said I need someone to design the line and someone to help me promote it.
