If you want to make money the only real way to do so is in the food market and provisioning supplies. Look around for things that sell for around 300 or so gil on the auction house and then find the monsters that drop them. Night milk is pretty expensive on my server at about 500 gil a pop and you can get them fairly easily from buffallos. Alternatively you can level botany and keep an eye out for whatever food material is in short supply. People farm apkallu eggs pretty frequently so you should look for whenever that camp isn't taken because they are a key ingredient in la noscean toast, omelettes, and deviled eggs. The key is to make sure you are checking the market wards frequently for what is either out of stock or in high demand. There is money to be made, you just need to know where to look for it. I started looking for ways to make money about a week and a half ago and I have made around 2.5 mil total while spending about 200k just to finish a luminary tool and a bit more on an HQ goldsmithing set because I was dumb and settled for NQ on launch. MAYBE if you hadn't abandoned me for balmung I could help you make some money but since I don't know what the economy is like on your server I can't help too much outside of what I just said.
The big issue is simply the fact that they released the content the way they did and we are going to have to wait about 6 months from launch for them to release the next real big set of content for end game. My assumption is that they will probably release the next tier of tomestones and crafted gear at that point with the possibility of a higher level of materia and that will probably be the next time anyone can make any sort of real money if it isn't their primary goal.
