Smith/Miner is the best for a new player.. almost no risk and all profit.
Disagree - make a pally/sampire and kill monsters. Thats the best way to supply a crafter. Crafters at early stages require resources to build skill. Even bod filling is near a zero sum game when you factor in resources to fill the bods.
In most cases you are better of selling the ingots than the time/materials to fill the bod. Mine ingots and sell. Mine in a guardzone in fel like Cove and make mad money with ingots. Thats zero risk moneymaking.
Otherwise, get a fighting character, get someone to make you a 70 resist suit and go kill things. Plenty of loot happy monsters. Whirlwind and low level of a rat spawn for mad spined leather from lizardmen. Shame earth elementals for gold and ore and items you can unravel. Probably make 1-2k per earth ele in shame.
And just for giggles - Hunted 10 Earth Ele's in Shame with normal suit, no luckon me. The value of items total in parenthesis based on lowest price listed for GL on SearchUO:
(2,503) Gold 2,503
(110) Iron Ingots 11@10 per
(4,000) DC Ingots 8 @250
(3,025) Shadow Ingots 11 @275
(525) Copper Ingots 3 @175
(25,000) Relic Frags - 2 @12,500
(23,750) Essence - 19 @1,250
(11,200) Residue - 28 @400
Total Value : 70,113 or about 7,011 gp in value per Earth Elemental
Your mileage may vary depending on drop rates of diff ores and loot items. It took me about 2-3 min to gather this with a 120 dexer - maybe longer with a newer player but still - should be able to make 200k or more of item value per hour easy. Yes, you need someone to unravel the loot for you but make a friend.
Also, even if the values here don't hold for all the items - you should be able to sell for at LEAST 50% of value making it at least 3,500 gold per earth ele which adds up pretty quick. Dexer suit and earth ele or elemental slayer and you are good to go.
Also did it a diff way - killed only Earth Eles for 6 min. Here is what I got (not counting any loot from random mud pies in my way) :
(5532) Gold 5532
(330) Iron Ingots 33 @10
(500) Dull Copper Ingots 2 @250
(700) Copper Ingots 4 @175
(1250) Aggy Ingots 5 @250
(800) Verite Ingots 2 @400
(50,000) Relic Frags 4 @12,500
(36,250) Essence 29 @1,250
(22,400) Magic Residue 56 @400
(30,000) Anti-Virtue Dungeon Arty worth 1500 turn in points @20 gp a point
Total : 147,762 per 6 min or 1.47m per hour
And because this is so much fun... did another run today. 10 min total including time to go home, unload and go back. This time looted the mud pies as well.
