Still thinking about the goods & services available at a Trading Post. Any comments, or further suggestions, are welcomed
Tire repair:
This may be a promising local industry - and one that even low-tech communities could manage
(see the link for a 1930's view)

Insect Killer & Harvester:
In a world with giant insects (most of them pests) this could be a useful trade. Chitin (the main component in insect exoskeletons) is used in various adhesives and can be made into surgical thread. It's also a good fertiliser and has several medical uses

Crowman:
Building mechanisms to scare off (giant) crows and other pests is an honoured skill in agricultural communities - and one that might include Witches/Warlocks. [also, quill pens might become common again]
Snake Handler:
The Smother and Timber Rattler would make excellent "guard dogs" (especially if the community has a problem with something like Maggots).
