I've read "Do things that don't scale" and "Ideas are worthless; execution is everything", so I'm putting this out there to hopefully obtain some good feedback and direction.

I want to create an art marketplace that sells original works. Signed or unsigned, the work would be original and potentially from a set (limited number), authenticated by myself with the support of the original artist. No prints or mass reproductions.

In Model 1, the artist would hold the item, but have an agreement with me to place the product on the marketplace. At time of sale, I would be responsible for (somehow) transferring profit to the artist, and the artist would be responsible for packaging and shipping the product. Pros: I'm not touching inventory. Cons: I lose control of photos, which provide the consistent "look and feel" of product listings. I would also rely on artist to ship timely.

Model 2 - have agreement with the artist and list the product. The seller would ship the product to me. When sold, I would provide payment to the seller, and ship the product. Pros: I would have full control of the product photos, and timeliness of shipping. Cons: I'm responsible for storage of all inventory. I'm responsible for taking all photos (lots of work). I'm responsible for product damages before consistent photos of the product, but would need to store the product until it sells. If it doesn't sell, I have to ship it back.

On the topic of doing things that don't scale, a small marketplace that will at first suffer from the classic "chicken and egg" problem will be manageable for me, but I'm not sure about the logistics of the two models. I would prefer to never touch inventory.

Will Shopify support what I'm trying to do? I know marketplaces are tough, but people have been able to achieve it in the past. I want to execute on the idea but do it smartly and obtain feedback from everyone here.
