Just so you know - you don't have to buy a bunch of tools for DIY juice. All I use are syringes (the kind without the needle) and empty bottles (I just bought a pack of 10 ldpe unicorn bottles from Liquid Nicotine Wholesalers for $5.00)
I rinse out the syringes and re-use until the writing is gone, and that takes a while.. plus, they are inexpensive to buy. You can even pick up some various sizes at places like Tractor Supply and not worry about shipping costs. You need a handful of 1ml syringes, and a couple of the 3,6,10 and 20ml..
nothing else is needed. Just shake the bottle of juice periodically while it steeps.. no big deal, no equipment necessary.
The other stuff makes it easier perhaps, but it's not like you need a bunch of stuff for the basics.
You can get a couple two or three ingredient recipes from people right here on this forum..
You can do this, even broke.
