Stevia-Sprouting from seed tips... please >>>

I just ordered some Stevia seed from Johnny's. I am interested in growing it and learning how to make Stevia oil [as a sugar substitute].
I have never been able to get Stevia to sprout from seed. Does anyone here have any seed-sprouting wisdom they can pass on?
I live in Southwest Michigan. Does anyone have any experience with bringing Stevia indoors for the winter? How small of a pot can I use [from garden to pots for indoors?]
Basically this could be a thread for All Things Stevia. I am serious about growing a bunch of these.
