Murraya paniculata, hoya serpens, Optimara african violets

Hello,
I'm looking for several houseplants:
1) orange jasmine - murraya paniculata - seeds, berries or young plant,
2) hoya serpens,
3) african violets (saintpaulias) - Broadway star trail, Optimara My Love, Optimara My Joy, Optimara My Passion, Optimara My Desire - haven't seen these Optimara varieties in shops yet.
I'd like to swap for smth. I have,
and I have many varieties of african violets and streptocarpus - can offer leaf cuttings,
hoya curtissii, h.lacunosa, h.panchoi,
several fuchsia varieties - rooted cuttings.
