dam sounds like you have been playing a lot!
With that armor, maul, horn bow and tartar arrows you should make money.
With only 50wpf the longsword may start costing you a bit.. (if you can maintain x3 or above for most of your play time you should be fine).
Edit - If your build allows it increase your 2h wpf.. longsword is 2 slots so you can only take 1 set of arrows.. So a lot of your play will be melee (presuming you have, or will have, 6 weapon master you should be able to get 86 wpf 2h at level 30) I think this will be worth it for the melee and the upkeep.
