Metal Roof Gutters

Hi, I bought a new home and it really needs some gutters. However, I've been trying to research this and I haven't come up with very much. One company I contacted said that they don't even put gutters on metal roofs because of the snow and ice issue (I live in Utah). Anyway, I'm thinking of taking this project on myself if I can learn enough about the intricacies. I've provided a picture so you can see the small amount of overhange of the roof. Do you guys have any ideas or recommendations?
