I've thought about this idea before, and the more I think about it the more useful it could be.
The idea is that once you have reached the master crafter title/achievement, you would unlock a third tier of writs. Players could list the gear/furnishings they want crafting and the price they are willing to pay and then master crafters could take the writs, create the items and turn them in (possibly via Rolis). This would make crafting commissions so much easier than having to find players who can craft via zone chat/guild chat/discord/forums etc and then send mats via mail.
This could be a substantial source of income from those with the master crafter title, without having to search for requests and trust the players who may be randoms. It shouldn't add any inflationary value, since the price the gold is coming from another player and not being generated from the game. It would also add some immersion to the master writ system as you would be creating items people actually want rather than random items for non-existent NPCs.
It would also be good if you could do partial fulfillments, so those who can craft some of the requested items but not all would be able to get the gold for the items they can craft, rather than being prohibited by not being able to craft them all. e.g. someone has a big furnishing request and you can craft 9/10 of the requested items.
I would assume that the writs would have to have some sort of time limit, say 24 hours, to stop people from taking the writ and not completing them, or two people taking the same one. By requiring a master crafter title, it should deter people taking down the writs to grief, or new players taking them by mistake.
