'Little' problem with my currency (Guiles)

guiles? gils? it doesn t really matter

I see you are lvl 11 arcanist and it is your only adventurer class.
Leveling your adventuring class, doing the story will grant you around 200k gils by lvl 50 (if you don't spend beforehand)
Follow the story quest line until you have to do the 3 first dungeons, to allow airship travel. Even to unlock the Grand Company and your chocobo.

This will help you traveling to find and gather what you need for crafting/fishing

EDIT : doing dungeons is a source of income. Find some players to farm them when you are at the correct level, or a nice FC (Free Company), it s a guild of players
There is a tool to search random players but with friends it s better.
