SkyRe makes stuff pretty expensive actually (90g/Iron Bar
with Imperial start at 25% cheaper)
Don't know if you'll do any thieving but
Shenks Overhaul adds a load of valuable stuff to houses/farms/castles, and a load of other cool stuff (not been updated for a while, but works fine for me... except guards don't spawn in some vaults sometimes, still need the hard to find keys though
)
Easy Pocket Money makes Jugs and Bowls worth more than 5g (50-100g I think)
There's also a
player shops mod, not tried it so far, the npc's for buying the shop show up but not owned a house where I need to.
