DIY juice is easy to make and takes very little experience. Recipes are available online and you mix by weight. It does take some safety precautions as nicotine concentrate is very poisonous, but if you don’t want nic all you need is PG, VG, and flavoring.
I started DIYing years ago and never looked back. The only large initial cost is the nicotine, which you buy in concentrate, but the overall cost when you make your juice is cheap as hell. The rate I go through it I have decades of nicotine and my cost per ml is ~6 cents. Most of that cost is the nicotine.
I’m lucky enough to be working with rather than for, but it does mean interacting with their crappy programs and work culture. Going back to using teams is a relief.
