As far as supplies go, you can look at myfreedomsmokes, wicked, and a hundred other vendors for nic base, PG, and VG. Stick with 100% usp grade PG and VG, and you want to be careful with your flavors, stick with reputable companies that deal in strictly natural extracts with no or as little as possible coloring, beware of the obvious bad additives (diacytle and the others...) and concentrate on what you are really looking to do. Are you looking to save money, craft your own special brew, or design something that you could possibly take to market? Mix in small batches (trust me on this one, it sucks to mix up what you think is going to be great only to find that after steep the stuff would be better as air freashener than e-juice...) and then, when you've mixed, breathed, ad steeped it, vape it on your regular rig, if its good, bump up the quantities, if its bad, then play with the percentages and try again

I use the e-liquid recipe manager lite, which can be found in the playstore if you have an android device, it is simple and intuitive, and allows for small batches. I tend to stick with either Flavor Apprentice flavor extracts or Loran

as far as containers go, if your favorite liquids come in glass, re-purpose those suckers and bottle your home brew in them! Careful with plastic, as it can hold previous flavors for a long time even after boiling! I hope this helps, it is simple to do once you've got a juice calculator and your compounds in front of you, lkw anything else, preping for the mix is the key, a nice clean area with your measuring implements and compounds and containers ready to go so there is as little fumble factor involved as possible
