Ok so I'm making a gold/profit guide to release in a few months and I decided to release a section of it here.
[Spoiler]
4.1 - Making 50k a week on a fresh server
Requirements: 1 vanilla account, A cataclysm enabled account (wotlk may work for lower profit of 25-30k), A lvl 25 Guild (preferred but a lvl 1 guild will work) with GM access, a lvl 55 or higher toon (Optional it's just for making a deathknight if you want to make one),Bulk buyers,A water walking/noclip and teleportation or speed hack.
Total Startup Cost: $70 or less
Total Ban Risk: 0% if done right.
Alliance Version:
If you have a lvl 55 or higher toon create a deathknight and go through the starting quest, if you don't have a lvl 55 or higher toon make a lvl 5 toon of any class/race and deliver either toon to menthil harbor next to the fishing trainer or under the dock if you wish. If you can spare the 100g getting full tackleboxes is a good idea as well be needing them later. On your vanilla account you should be scanning the auction house for fish prices on your market and try to figure out which would be the most profitable. It'd also be a good idea to use a mailbox hack so you can just mail your stuff to your vanilla account for auctioning and not really have to move much but if you want to use a mailbox there's one within range near the inn you can use. Odds are by the time you level your fishing maximum here (You will be here from 1-525 fishing because it's the most profitable area to train your fishing with a fishing trainer within train range) you'll have a decent amount of gold (Should be 2.5-3k).
Items to keep:
All of the crates : between 5-20 gold per crate
Oily Blackmouth :40-50g/stack
Firefin snapper: 40-50g/stack
You may cook and vendor the spotted yellowtail if you wish. Otherwise just vendor them they're next to worthless and sell for between 3-4g/stack. If you want to attempt to sell some go ahead but hardly anyone buys them to level cooking over deviates and other 100 cooking recipes.
Now that you're 525 fishing and have some coin in your pocket grab 4 tackleboxes if you haven't already and head to the following areas based on price:
Uldum Coast Under Boat:
Contains: Deepsea Sagefish,Fathom eel,Murglesnout (vendor),Azshara's Veil, Volatile Water
Outside:
Inside:
Deepholm Crater:
Contains: Angelfin Rockfish,Volatile Water,Lavascale Catfish,Albino Cavefish
Inside:
Outside:
Pick the best method based on your servers economy and enjoy your 50k a week on a fresh server!
Alternate Farming Method:
Requirements: Flying mount, wotlk enabled account with at least a lvl 55

I will eventually include pictures in the guide and format it a little more but that's pretty much what it contains in that section. I'll probably be releasing an alternate method as well. And one for horde once I figure out an alternate method to tanaris (Since steamwheedle port isn't there anymore)
