Iksar Faction Advice

[NZV]

Hey there, I just started playing again and made an iksar shaman to play with an SK friend of mine. He tends not to have quite as much playtime as I do though, so I figure I'll work on some factions rather than outlevel him.

The one I'm most interested in right now is the west/east freeport guards, and I'm wondering what the quickest path would be to boost that up to at least dubious, and around how many belts/scalps/whatever I'd need. Losing NFP faction isn't much of a concern since it seems pretty easy to get Neriak faction if I need a bank close to the tunnel. Similarly, anyone know how much red wine I'd need for Neriak? Any info would be fantastic.
