I'm always happy when someone turns their hobby into a business.
I congratulate you on this and I wish you all the best.
Before recommending embroidery machines for your business, I would like to recommend some for you to read about business.
If it's your first business, for sure there are a lot of things you don't know about managing it, but which can get you in trouble later.
And this is because most of the time, when we go from hobby to business, we are good at the activity, but they are stupid at managing the business, or even at planning it. That's why I strongly recommend you to reserve an hour and go through the resources above.
