HI
@slinkey97 and welcome to the forum.
If you're thinking DIY I would suggest reading as much as you can. You will use 3 or 4 times the vg as pg, because when you add the flavors (most are in pg base) the ratio of PG in the juice goes up by the percentage of flavoring.
I would suggest checking these sites for recipes and making a shopping list. Different manufacturers CANNOT be substituted, you must use exactly what the recipe calls for.
