Here is a post thanks to Selltacular. Without him, I never would have been able to get to where I am. This is a guide on how to get into the glyph market, to the extreme in my case.
So, where do you start? Selltacular made us a great post with groups to start with. This enables you to have a giant blank for posting and cancelling items with the use of an Auctioning operation. Without this, you need to post and cancel by hand.
Now, I made every glyph that makes me profit and three of each. A bit overkill, maybe. But I wanted to just take over the whole thing. This way, I can have nearly every glyph in stock at one time and not miss potential sales. Using TSM's Crafting queue, I just added three of each glyph until I had them all stocked up. Took a fair while to craft, but definitely worth it.
And that was basically it. I used my Auctioning operation to post them all, and the rest is history as they say.
