I would think that a selling relationship with some of our sponsors, who craft things like leather goods that are not available in the bigger stores, would be beneficial. I get tired of seeing the same old stuff at the bigger vendors' web stores, and like the uniqueness of more custom or handmade products.
Also, a YouTube channel would be helpful. My dad ran a shop for many years, and one thing that kept it going was the patrons who just wanted to stop in and shoot the breeze. A double edged sword, that, because if they always talk and don't buy, there's no money changing hands. But if you could capture that atmosphere somehow in a YouTube channel, you'd generate a lot of interest and traffic should follow. You might even sell ad space for some trad companies or products.
If I had a shop, I'd consider setting up an HD video camera full time, and turning it on to catch certain things that I'd like to show on YouTube, from conversations, products, activities, or customer interactions.
I wouldn't go into it expecting to get rich, but it might make for an interesting hobby.
Just some talk, and talk's cheap...
