What you're going to be doing is grabbing inscription and putting it on any alt, even if it's a level 5. Next, level inscription to 75, at this point you'll have access to the minor inscription research which will allow you to learn one new recipe every day. Craft the most profitable glyphs everyday and list them at the auction house, alsso do your research everyday until you have all of the minor glyphs. There is a total of 64 minor glyphs that can be learned.
The best part is that you're spending little to no gold crafting glyphs. If you have 25g, you could buy a couple stacks of herbs, mill them, craft inks, then craft the best selling glyphs at the auction house. You'll be turning that initial 25g investment into 100g+ in a matter of seconds.
If you haven't heard about it already, pair this up with TradeSkill Master and you'll be crafting, posting & cancelling with minimal time spent. There are a ton of guides out there that will teach you how to properly set up this addon if you've never heard of it. It does take up some time to set up, but once it's set up you'll be saving yourself from hours upon hours of time, trust me.
All in all, this is one of my favorite ways to make gold on my alts that on a different server than my main, especially once I learn most of the glyphs - it gives me access to a more diverse market that I can profit from.
