Ebay and Etsy will get you designs of varying quality and production values when it comes to embroidery digitizing.
Is that viking a part of someone's logo (I see other embroidery objects in the bottom of the picture, likely some type of brush script, so maybe just monogramming?) or is it truly a stock design? Going for stock designs, I would go to places that may cost more then Etsy (Dakota Collectibles etc), but usually have better production values.
Last option, if you can't find the exact stock design (if it is a stock design), get your client to get a good straight on picture (with the exact measurements) and any digitizer (person) worth their salt should be able to replicate that.
