[NM] Niche art studio / retail / manufacturing

I own a small building that houses various art related studio projects including a glass art (lamp working) studio, wood shop, welding shop, laser engraving, photo, and 3d printing. I also have a small public retail selling glass art supplies (300sqft, under 50 customers a week). I have 3 employees counting myself, one is a one day a week bookkeeper who maintains a small office up front y wife), one who runs the retail side with me, and both of us blow glass in the studio.

My current policy is poorly written for what I'm doing these days, and talking to other people in the glass art industry it sounds like it could be difficult to find an appropriate policy that covers a glass art studio, let alone everything I'm doing with my business housed in a building I own.

Any advice on how to go about finding a good policy that will give me the coverage I need across various aspects of my business? I need to make sure that my building is protected, my employee is protected (I do have a separate workers comp policy), and most importantly the general public who may come in as retail customers or participants in classes in a glass studio or to collaborate with us on projects.

Thanks!

ETA: I own the building through an LLC, the LLC has a separate policy that I feel is appropriate for the building and other tenants. My business pays rent to the LLC, all arms length transactions, looking for how to protect my s-corp retail / studio mostly…
