I kinda ment for this to be a secret, but it came out as a request, whats up with that? Anyway here are some ways for beginners to get rich.
1: If you are able to hit very often in the vivec foriegn courters plaza, there is only one guard. So you can kill him, take his armor, sell it, and do it all over again.
2: If you have a good amount of money go to the zeniab ashlander cam , and find Ababael Timsar-Dadisun in his hut, train your mercentile up 100, and then go to balmora. Talk to the trader, buy his 'daedroc' weapones, you will get them for a lot less then what they are sopposed to be. Sell them to the creeper.
3: Find a daedric shrine, kill the dremora, take their weapones, go out rest, come back in the shrine, and kill them again untill you are overencumbured. sell them to the creeper.
4: Who says theiving never pays off? If you go to vivec, the hlaalu, redoran, and telvanni cantons have voults. if you tount the guards, or do whatever is needed to kill them without a death warrenty, and you find the key to the voults, once you are in there, there is money everywhere! (Or atleasts a lot of expensive goods)
5: This isn't as much a way to make money, as much as a tip, but it works anyway. If you are skilled in sneek. (If not the master trainer is in Drough Jiggers rest in gnaar mok) And find an item that belonges in the mournhold musium, you can sell it to the lady in there, and then just steel it right back. (But don't sell it back)
