As you said in your query this is a digitizing service.
You would supply them with a photo in jpeg form and they would digitize it for you into the PES form for your Brother embroidery machine.
If you have something specific you want digitized I believe there are other reputable companies out there. I have never heard this company.
If you are looking just for embroidery files to purchase there are so many reputable companies you can purchase from and so many items to choose from.. I would start with what is on your machine to learn how to use the machine and then branch out to purchasing new embroidery files. Many are very inexpensive. I would not buy anything that is to complex. There can be many color changes and can be quite daunting for a newbie.
I do a lot of embroidery and digitizing and there is a learning curve.
Have fun.
