Oh wow, nic free, you'd be paying well under a dollar for 30ml.
You can get a gallon of PG and VG, each, for about $20, flavorings for about 10ml to start out and see if you like it, can run between $2-3 each, depending on brand. You can get sample sizes, usually, for under $2, that will actually last you a decent amount of time. Syringes can run about 60 cents each, or you can get a decent scale for under $20, easier clean up, but for bottles that don't come with a dropper top, you still need a few syringes. Bottles, depends on it you want plastic or glass. There are good deals on both those, too.
All in all, you can get quite a bit for $100, or less, especially since you may not be purchasing nic. If you want to spend less than that, you can still get all those things in smaller sizes, till you figure out if DIY is for you. It's addicting!
I shop Bull City Vapor, Ecigexpress, RTS Vapes, occasionally, eliquidmart, and Nicotine River has really good deals on flavorings, too. Wizard Labs has started carrying more brands of flavorings lately, and in sample sizes. Most of these places will also sell the rest of what you need, except a scale.
There are other places if you decide you'd rather buy bulk sizes.
