The economy isn't as bad on red as you think, the killer (especially for a SK, and the reason I haven't rolled one there yet) is their gear to buy is very overpriced because every man and his dog wants in on the SK action for alts etc.
If I could log in (library internet is all I have, and it won't let me) I would make you both up some JC slot items (HP rings, +wis ears for the shaman, +sta stuff for the SK, and +MR bracers for the pair of you).
If you're not guilded it might be worth trying to find one to help you out with bigger groups, but if you're definitely happy as a duo I'd pick some quiet cash camps.
If the shaman is evil (most are), consider these spots:-
32-37ish - Halfling guards in Misty Thicket (watch out for Ella Foodcrafter roaming out of the gate)
or 32-35(?) - Ocean of Tears named sisters. You might need one person to run a vendor mule out there to sell the swords they drop but after that short inconvenience it's a good camp. There's a lot of pvp in this zone but not at your level, mostly at seafuries.
38-48 - Spectres in Feerott (less traffic there compared to Oasis, and if evil you can likely sell outside Oggok)..."Scythe" sells for about 12pp, "Bronze Scythe" for 3-4pp
48-54 - Highkeep nobles/bard NPCs/Isabella Cellus (will trash your Freeport guard faction in West/East if you had any to begin with), they drop gems and such...and you can snack on green guards for FS weapons if you're waiting between the 6 minute noble respawns. Sell at Tarn Visilin (next to Justin Rhymes the bard vendor).
54+ - the shaman will be in his/her element now and could probably solo, but I'd consider extending your duo to a trio with some dps (monk/rogue/mage/etc) and hitting up somewhere like Velks. KC is doable but be prepared for a lot of pvp, same for seafuries in OOT
