Hermione has no idea how mages actually come to acquire their staves, though she'd always assumed that, like wands, they generally came from a shop run by someone considered to be a master in his or her field. It's part of why she'd agreed to work with Adelaide, really. She doesn't need much in the way of food or proper shelter considering her year of largely going without, but if she could pay a staff-maker to fix what basically amounts to her tiny staff, she'll feel much more comfortable wielding her magic for more than just basic spells.

"Back at home, the wand chooses the wizard, as they say. Every wand is a unique match to the person who wields it, and many people generally believe you can tell what sort of person a witch or wizard is based on their wand. Do staves work the same way here? Because it might be a bit difficult finding a match, in that case."

After all, how can a staff match up with a person who doesn't even get her magic from the Fade? It seems counter-intuitive, which is part of why Hermione hasn't actively gone out looking for a staff, despite the repeated suggestion of it.
