They've got an online designer, though I found that the bleed area I added got trimmed to the exact outline of a label, so prints can have thin white edges. Otherwise they are slightly trimmed versions of the full size labels someone posted here already.
The numbers were added with the csv import feature in the label maker.
I don't have the source artwork any more, but if you have the logo it should be literally minutes to set up in the online label designer.
I've got these PDF printouts, but as I mentioned before it would be better if each label was slightly bigger than the cutout on the sheet, so alignment errors don't show up as white border. I just printed the first page, which was more I needed.
