I agree that has a ton of potential.... IF people will buy it. I still bet the goods caravan makes more money over the course of 1 month. The crafting business will quickly be undermined by alliances and internal production. What can you make that's worth buying that absolutely nobody in my entire alliance can make and will sell to me for little or no profit?
I do hope there's a market in crafting goods but I can easily see it being something every alliance does for themselves, instead of buying.
Crafting was a valid way to make money in EVE because it was such a huge pain that most people wouldn't do it. They would rather just farm up cash and pay someone else to craft. And EVE fostered a lot of independent players who simply wouldn't have the resources to run their own crafting operation. The crafting in this game is so easy that everyone can do it, and there's no reason to even be in Strategus without a clan.
There may be some market in being able to craft things that most people can't make, though... like "Round Shields". Who has points in that? Better yet, who has a +3 "Round Shield"?
But I think whatever you craft and sell is going to be some niche market stuff.
As much as people can craft the goods themselves, there will always be a market because people can't produce them as quickly as they would like. Whether or not you can create hierloomed longbows for 130 gold per at 100% efficiency that's only 24 bows a day with an expenditure of 3,120. Now, along comes the Caravan Guild having heard of your attacks or defence of a location, and you need equipment and you don't have time to craft 100 more bows etc, alright well, we can give you those 100 bows at 180 per in 5 hours, that's 5,000 more for a massive decrease of 95 hours providing you even have 100% efficiency.
With good infrastructure, negotiated trade routes & stockpiling you're going to be able to happily get the goods in time and make sure that it's given to the right people for a reasonable price.
The price margins don't seem great but depending on how much you can actually create the items for, the money will come roling in. They spend a bit more money for an increased efficiency while you gain more money. I'm sure everyone can understand the basic maths behind it and have enough business skills to see how this can be profitable while negotiating, the figures above are completely made up and of course and not like to be real. (Other than the efficiency and the number than can be created)
With bulk orders of equipment, for items that are in high demand because of their stats, use and general availability within cRPG, therefore more people are familiar with using them, you're going to have a decent increase in the number of people wanting these goods within a given time limit. As long as you've got your infrastructure in place, you're able to make the money much quicker.
The risk is much lower since you don't have to run across the map and the fact that you don't have to keep changing things around and being active nearly 24/7 warrants for much more money for much less effort.
With the "niche market stuff" this won't be so good, I mean, everyone is going to need decent weapons at some stage but there is no point having people craft long daggers because there is practically no use for them.
Probably the most niche thing that we have is heirloomed hammers, much cheaper and more effective to just buy these from the basic town markets as base level than to commission someone else to create them at an heirloomed value unless you're making ridiculous amounts of money.
