Thee are many breed selectors on the internet which will help you find a breed which suits you based on your schedule, ability to care for the dog and so on. It is not perfect. you will still need to reasearch the breeds. But you shouldprobably try a selector ( or 3!) and look at the top 5 breeds which come up for you.

Here are some links for breed selectors:
