4th and 5th level NPCs get 3300gp and 4300gp respectively. So masterwork spear, +1 breastplate, masterwork +3 mighty composite longbow (total cost 2200 gp) is well within reach.
It comes to a tad more than 2200 gp though...
Masterwork spear 301 gp
Masterwork composite longbow 700 gp
+1 breastplate 1350 gp
Total 2351 gp
We'd want to use the 5th level 4300 gp wouldn't we, since they've got a +1 CR adjustment.
That leaves 1949 gp. How about a +1 cloak of resistance and a few potions or oils, such as oil of magic weapon, potions of cure light wound, shield of faith, or enlarge person.
