i prefer using blizz sorcs over light sorcs you tend to find less cold immunes then light immunes + you can also do a decent amount of damage.
gg guide:

or if you cant be bothered to read all of fraters you can use my one, but i suggest using fraters because its alot better.
mine:
Helm- Shako 'ist' (75mf)
Armor- Tal's 'ist' (113m)
Belt- Tal's (try to get a 15%mf one) (15mf) (Set bonus gives 65 mf)
Amulet- Tal's or maras
Gloves- Perfect Chance Guards (40mf)
Weapon- Occy 'ist' (80mf)
Boots- Perfect War Travs (50mf)
Ring#1- Nagel [30mf]
Ring#2- FCR + mf ring
Shield- Lidless 'ist' (25mf) or if you've got enough strength go with spirit (requires 156 if in a monarch) and use a 30 nagel as your second ring.
Switch- CTA (6 bo) & Lidless or if you have enough strength spirit
Charms: 40mf Gheeds, lots of 7mf sc's, anni, and torch
Mercenary:
weapon: infinity
armor: fort
helm: andy
Total magicfind: 533 with gheeds + wateva mf (from sc's) + wateva mf (from fcr ring) you will easily reach 600mf or higher if you add in your ring and charms. You could go higher by switching the gear a little, but this setup has high mf, decent killing power, and fcr for mf'ing. If you wear 20 7mf sc's, you'll have 673 mf (i think), and you'll have room for more charms.
You will reach:
MF: 743 with 30x 7% mf sc's, 673 mf with 20x 7% mf sc's
Stats:
strength: enough for gear
dex: none or enough for max block(only if you want block)
vit: rest
mana: 100 with out gear
Skills:
Blizzard: 20
Cold Mastery: 20
Ice Blast: 20
(Basically max Blizzards syenergies)
Teleport: 1
Warmth: 1
