I found this great shop in one of my teams the other day;
They offer tons of really helpful options for getting your shop up and running to just tweaking a existing shop.
They can help you with SEO, which I could use. Can redo or even give you a new shop banner, business cards, and can even help you with design of your blog to make everything cohesive. If your shop is in need of revamping, I would highly suggest you go here and see if they can help you, because you just never know what they might come up with to help you make those extra sales.
