Some possible ideas:

* If possible, it's a good idea to ask the previous homeowners who they have used or recommended for tree/plumbing/etc work.

* You could ask your neighbors who they have used in the past, or if they have any specific suggestions.

* You could ask people on a neighborhood social network (such as Nextdoor or Facebook, if you are on those platforms).

* If none of those work out, Googling or Yelping like you said also works. There are also apps for this, such as Angie's List, TaskRabbit, Thumbtack, Porch, etc.
