You'll be able to sell all the non-magical items in Hommlet, one way or another.
The Smiths, for instance, lack cash, but will probably work a trade with you where they'll give you a masterwork dwarven waraxe and a masterwork warhammer and adjust your MW Full Plate armor in exchange for the rest of the non-magical armor and weapons you found. It will work out to be the same as if you had sold the armor and weapons, but nobody in Hommlet would have had the cash to actually buy all those items for gold.
Selling the magical items will be a bit tricky. "You see, I found this item in an ancient crypt and took it away from some evil cultists. I don't know what it does, but I want more money than you have ever seen for it."
