I believe there is an artisan alchemist in Darnassus that can teach you into the expert level alchemy (+150 I think), then a Master Alchemist in FeatherMoon for Artisan training.
As you no skill ups if you are making items below your skill level, skill ups will be far and few between. If all your recipies are showing as orange/brown including those you know you are well past, then likely you are bugged, petition about it.
