I don't think they have all that you wanted, but what they have has surely helped me in understanding the notes.
I'm sure that the lavender in this form will smell more like the lavender in perfumes than the pure lavender oil would.
You can do a search and find lots of places that sell essential oils in one oz. amounts. The prices can be quite inexpensive or rather expensive--it depends on the product.
