I tend to make my own wax finishes using beeswax and olive oil. It's just one part beeswax to three parts extra virgin olive oil, and two or three drops of essential oil if you want it scented. Just bring the olive oil to the boil and add grated beeswax chips. Stir until melted, let it cool a little bit in the pan, then transfer to heat-proof containers to cool (I use left-over Tupperware from Chinese takeaways).
I don't know if you'd call it high gloss, possibly not, but I've found that it's just as good as BriWax and you can also say that it's organic, so long as you're using organic oil and beeswax, which is attractive to some customers.
