People should be able to see what furniture they can get besides just the Guild Master. Leave it so the Guild Master is the only one that can buy but right now no one besides the GM can even know what is available to get besides having the GM either tell them. They should also be able to preview furniture so they can see what they look like before buying it so you don't end up buying something that either doesn't fit with what you are trying to design especially when you are buying under a budget look most guilds.
This will allow people to be more creative, buy more furniture since they know what they are getting and allow other people in the guild to pitch in their ideas since they can all see everything that is available instead of either using their imagination, having to buy the furniture first just to see what it looks like, or having their gm describe it to them.
everyone in the guild hould be able to preview the emporium, and only the officers and guild master get to be able to use the funds to buy it. also, have for a way that if an item is placed in storage, and a guild mate wants to remove it, make it so they have to get the guild masters of officers consent to remove it so things wont be going missing without anyones knowledge. also have the record take down who deposit or takes from the storage.
