To summarise the TL;DR guides:
- Level each of your crafters in line with each other so they're sync'd and you're able to craft any materials you need.
- Unlock all of your beast tribes as they have essential materials that are used in crafting recipes up to and including Level 35.
- Buy materials from beast tribes, as these will in most cases alleviate your shard consumption, and typically the cost of shards... Crafting the Velveteen Cloths is more expensive than buying the cloth from vendors alone, in shard consumption alone. Assuming you buy shards and not farm them.
- Most people will hate me for this, but don't bother touching leves unless you're capped or at Level 35+. This is where materials start getting tedious and where buying them is more expensive. So save your leves for this period, as this is also the level range in which you can start to get consistent HQ compared to Level 1-30.
- Save doing ixali beast tribes on your Culinarian and Carpenter, as these have the most important cross class abilities respectively, Steady Hand II and Byregot's Blessing, as such it is not a great issue if these get drastically higher than your other classes.
- A combination of beast tribes, and custom deliveries, and daily Grand Company turn ins will comfortably get you from 50-70 in the time frame of around 2-3 months assuming these are never missed

Some pointers here weren't relevant to the question, but are useful all the same particularly for low level.
