I hate these quests, so much that I've been skipping them so I don't have to bother. I don't think I've ever completed one, and for me at least, it's because they always ask for a very specific item, often one you have almost no chance of ever gathering enough of to complete the quest.
So here's my suggestion. Instead of requiring something specific, just allow for any item that fits the requested slot. So for example just "horses" instead of "chargers". Obviously you should be rewarded better if you bring chargers back, but I'd actually finish the quest if I could just turn in the next batch of horses I can fill up my inventory with, or weapons, armours, etc. Even if not "weapons" being as specific as "swords" would be better than "bastard swords", as I can usually find swords, polearms, etc. but almost never a full inventory of one specific type.
