AllisonB thank you for your suggestion.
Regardless, we would not consider a machine that had no way to convert from some standard graphics file format to their machines format.
Such a machine does not exist! You need embroidery digitizing software and lots of training in order to produce a stitch file that will stitch efficiently with no thread breaks, minimal color changes, minimal trims.....and look spectacular. Some people think that embroidery software with an "auto-digitize feature" is the answer...it is not. A good graphic is a great start. From that point on, there are so many variables to keep in mind as you digitize...the best way to sequence your objects, a way to hide travel runs, density of the objects in relation to the type of fabric you will be sewing, allowing for distortion that occurs with a circle for example....and the list goes on.
When I had my embroidery business, using top of the line Wilcom digitizing software, and the 15 needle Tajima Neo....it still took a lot of trial and error and experimentation and many samples to get some designs "right". For the more involved designs, I sent them out to a digitizing expert, and it was worth every penny.
You have a lot of things to consider before jumping into doing an embroidery business. I am thinking perhaps you haven't done a lot of research yet, because you would otherwise know a little more about how the process goes from graphic to stitch file. Not trying to be discouraging, but just wanting to say that there is definitely a steep learning curve with embroidery.
