I am wanting a plug-in created or maybe on has already been created. But I want to be able to type in chat /market or maybe access a box and a UI pop up. I want the UI to have a search function for the item you are wanting to purchase. Once you search for item all the sellers posts will pop up. You can then purchase the item for their specified price.. something like this could be really cool I think. I would be happy to pay for a developer to create this idea.
