Pacific AquaFarms, Quality Marine, Exotic Reef Imports, Sea Dwelling Creatures, ORA, Seagrest...and too many more to name.

All are good for some things, not so good for others. There isn't one supplier who is the best at everything.

She'll have to develop her own short list of suppliers based on what she is trying to offer. Quality Marine (qualitymarineusa.com) is a good one to start with. Overall good selection, quality, fill rate, and they are pretty good about crediting for doa's.

Ask around on the industry forum on reefs.org.

That's almost a straight answer right?
