So, now that I have hit 50 I have some time to begin crafting and gathering, but I'm not really sure where to start as I have not interacted with the economy a lot. So far the only thing I have considered buying is the Picatrix of Healing, but there are only a handful on the MB and those that have the materia are pricey.

So, where is a good place to start?

I need to get a gathering profession to level 19 so that I can work with Materia, but I'd like to invest in a profession that I will want to level and will do alright when it comes to buyers and currency. Not looking to be rich, but I do like to make efficient choices.

Based on what you know about our world, and your own experiences leveling, what would you recommend?
