I just recently maxed out my alchemy and herbalism on my warlock alt, and very quickly turned him into elixir-spec. Since then, I've been advertising my business in the trade channel, hoping to draw in some customers. My macro looks like this:
[Elixir Master] LFW! Need flasks made? All work done ~absolutely free~, I keep any procs that might happen. *insert witty remark here*
9 times out of 10, my posting in Trade is immediately followed by someone posting 'Alchemy/Elixir Master LFW, free with your mats and you get all procs' or something similar to that. Either that, or I'm openly ridiculed by people for keeping procs in lieu of a crafting fee, or called a thief and accused of trying to scam people.
My view on it is this: I don't charge to make things. If things don't proc, I don't make a dime. Procs are how I make my money. They still get the same amount of flasks they gave me mats for, and they get it done for free. I'm up front and honest about the terms of the transaction up front. And yet I still get haters constantly when I advertise.
Am I doing it wrong? Am I being unreasonable for running my alchemy business that way? I think it's a perfectly fair way to conduct business, to be honest, and I'm not trying to scam anyone. If anything, there's a greater chance for me to lose out by using it.
