I'd suggest you incorporate to your weeklys making a blessed wooden stake if you're a prem account, and a daily obsidian knife, both fetch a nice price, specially the blessed stake at around Hot Cuisine Anual event.
Bigfoot's Burden daily tasks will net you 12 minor crystaline tokens, also with a good price tag, for about 1h worth of time if you're unlucky.
Same for Dangerous Depths measurements and mapping tasks, for about 5mins of work you get 2 jars containing some valuables. Gold and Silver tokens are in high demand
