Manufacturing is not what you should do for gold, but gathering is a way to earn gold for you. Basic crafting Tools are available for you on the beginner monsters. You can find toolboxes near the beginner monsters who also have some crafting Tools. Gathering these Tools enables you to save a lot of money. Otherwise it costs you 20g a pop to acquire those gathering Tools from the Merchant NPC. Gathering Tools will return many times that if you are careful, and zero if you are careless and get killed while harvesting.
