You could easily DIY you own Vanilla flavoring using PGA and/or VG/PG. I've used this method in the past and it works really well, but time is a requirement. It's not a 2-3 process, more like 4-6 weeks to 3-6 months depending on what you use and how long you want the flavor to pull from the vanilla beans.
It's harder to find vanilla beans around here, at least at a somewhat decent price (stores sell 2-3 for $12 around here - and you'll probably use them all in a small batch).
Just a suggestion. There's quite a bit of information on Google/YouTube to make things easier and follow along with.
