Consider familiar master or the witch dedication if you want to draw upon that aspect. Witch is probably pretty good there given you have various themes to choose from and it comes with a familiar as part of the dedication. The familiar isn't as special as a full witch's though, it's just a regular one.

Could also be worth browsing through NPC core, although sadly there's only one low level apothecary NPC to look at. As far as paizo's slop goes, the overall book was actually pretty good though. Lot of npcs with interesting mechanics or borrowed class features.
