Pick up some empty 5ml togo bottles, pipettes, and perfumers alcohol to begin. I picked up around 100 pipettes for $5-$7 on ebay; empty bottles and perfumers alcohol from androtics.
Start with small batches. I use the mix calculator for all of my mixes except MX301 (Mix Calculator 4.0 : Software to make your own mixes)
It can be easy to waste the product when making a custom mix. It is fun but is best to hold off mixing until you have conducted enough individual research and field testing on the individual molecules so you know exactly how each reacts alone and with another.
