Buying guilds worth it? Also are profession kits worth it?

[Goodkareem]

So from what I understand in order to really have the space to make some real hardcore profit from this thing you need some extended space. I have been buying up guilds when I see them. I have two so far and in talks to get a third one for faily affordable price. While my toons run they invite unguilded. Just to pump up the numbers. I have been stockin up on a lot of random materials while leveling my gathering professions. I was thinking of selling some kits. What is a good price to ask? Anyone else using gbanks to move around items or is it a waste of resources?

Just to elaborate both guilds are level 25 with 7 bank tabs. One is actually close to getting the Stay Classy Achieve so i can get the 8th. If my math is correct if i can fill both of those banks with ore and sell out I can make 1.5 million g. My toon fills a little over a bank tab in 2.5 hours of gathering. So with three bots running I can hopefully fill those banks in about 5 days without even running the accounts but 8 hours a day.
