To find a tattoo artist who does Viking-style tattoos, research local tattoo studios, get recommendations from tattooed acquaintances, view the portfolios of various tattoo artists and ask about their experience with Viking designs. Most reputable artists have experience with a variety of styles, including Viking.
You may also ask members of tattoo-oriented websites and publications such as Body Modification Ezine for artist recommendations. When meeting with a potential artist and viewing his portfolio, look for elements of Viking or Norse tattoo styles, such as runes or the circular Norse protection symbol known as Vegvísir. Once you choose an artist, work with him to design a Viking-style tattoo that complements your body shape and conveys an appropriate meaning.
