I use a socketed Sunkeeper for low levels. I have built in with my chest and pants as well. I run mp0-1 w a leoric and hellfire as well so if you want there is another 40%. You could also get another 45% from an amulet but you have mf there already and is a decent piece.
Legendaries like Depth Diggers and Blackthornes are good and always come with Magic Find.
All things considered though you are better off gearing up to destroy mp1 at a fast pace and gain paragon lvls for your mf bonus. It will help you more in the long run. But if you are set on mf, id go DD/Bthornes and maybe get some on your Amulet as they can get 45 I believe. Other than that give your enchantress a Grand Vizier and perfect blue Mf rings and ammy. As mentioned above Sun Keepers can roll really well, but a good one is expensive.
