So my wife and I just finished our backyard landscaping. It looks great and I planned on doing the gardening myself but the lawn is very curvy with lots of edges and also has flagstone with grass growing in between and we've decided to get a gardener.

There seems to be a wide price range and we don't know how to choose. Any recomendations for good gardeners in the San Fernando Valley that won't break the bank? Thank you all.
