No offense, but I think you don't quite understand embroidery. First off, nearly all newer machines, except Barudan I believe, have USB input ports. It isn't a problem to transfer directly from a computer to the embroidery machine. Most machines also retain that design so that when you shut it off, it asks if you want to restart the same design. Now comes the hard part:embroidery and digitizing. Both have a learning curve and regardless of what anyone tells you, there is a lot to learn. You can't use the same file to embroider that you use on your cutter. Digitizing software can run into the high thousands of dollars and take years to get good at. The new programs do make it easier for a beginner, but they still take lots of time to learn and cost big bucks. If you've got the time to learn, it would be a great adventure. All of the good embroidery machines sell worldwide and you need to look for the best support, not a particular brand to start with. Just don't believe any salesman who tells you the machine does the work
Stay with a name brand like Brother, tajima, toyota, swf, etc. As for wholesale, you can just search wholesale clothing and come up with a bunch of companies. Most require a business license to buy wholesale. Go to a trade show if you get the chance, I'm sure they have them "over the pond" too. Be prepared to invest around 15-20thousand dollars for a good machine and software, unless you get the brother pr600. They are a good machine to start with , and even stay with in certain circumstances, and cost a lot less than the bigger machines.
