I paid $85 pp for makeup - me plus 3 bridesmaids - she was fabulous. We didnt do a trial either, I paid an extra $10 pp because she was travelling in the city from country victoria
Her daughter did my hair, that was $200. We did the bridesmaids hair ourselves (or rather, my sister did it lol)

So...
You + 3 BM + MOB + MOG @ $440 = $73 pp - I think that is pretty spot on. (Especially since you got to keep the makeup)
