'Little' problem with my currency (Guiles)

[Niwashi]

One option is to wait on crafting for a while. At around level 17, one of the main story quests unlocks the ability to hire retainers who can both hold excess items for you and sell items to other players. Once you can sell to other players, there are many items that people will buy for more money than you can get selling them to NPC vendors.

Oh, and another thing that will help is to join the Botanist guild. They also gather a lot of the items that culinarians use, so you wouldn't have to buy as many of your ingredients. For that, though, you'll need to go to Gridania, which means you'll need to unlock the use of airships with a level 15 main story quest.

In the meantime, you can earn some money through quests, FATEs, and guildleves, but yes, during early levels it can be hard to earn enough to support crafting. If you get your Arcanist up just a little further though, and advance the main story through the next few levels, it will get easier.
