PvM, Well if you solo your self in non ladder the best choice for you is a javazon, cuz it doesn't take much for them to be good and its norm, but if you do get rushed and baal and all that good stuff....
I sugest the bowzon :: Because all you need to do is pack duel LL on her and you can leach like a mad man with multi-arrow and strafe. You can use a ebotd hydra bow or other bow, and it should work great for you and its cheap cuz no one really uses it.
Since you don't have enough for faith.
You can use reg uni* gear for her and she will do fine, you can just slap on gloves with IAS, and im sure you can get your hands on CoH // **BUT**
If you are too poor for any of these items <IE :: EBOTD bow // CoH>
Don't bother with a zon, cuz it wont serve much servace in hell mode.
I would sugest getting a Mf-char firt.
I sugest eaither a Wind Druid (Good Resist and Really good at tanking//hard to use)
Hammerdin (Very strong and easy to use//cost the most)
Sorc (Good all around and very cheap//resist to monsters)

Hope this helps, i can answer anything.
