Greetings, I am considering hiring a landscape designer to recommend shrubs, flowers, and other plants in a large rock mulch bed in front of my home. Are there certifications or accreditations in this field that I should be looking for? Are there specific questions I should be asking a potential designer? Internet reviews are almost non-existent so no help there. As always, thanks.

It is likely that larger nurseries and garden centers would also have them on staff.
You could ask to look at portfolios of work that they have completed.
