It really doesn't take long if you just ran some dungeons as well. Seriously, even with just 1 character, running all paths of just 1 dungeon, you can get a piece of armor every day. If you ran 2 dungeons, well, that is 2 pieces. At most it should take a week to have full exotic armor, 10-11 days for armor and weapons. Now, say you have 2 characters that can run a dungeon, well cut that time in 1/2...
Seriously, it doesn't take long for full exotic gear. Once you add in the income you make in the dungeons, in that same time you should be able to afford to purchase exotic accessories, or the parts to craft them (AC you make 41s per path, not counting drops, so figure 1.5g for running the 3 paths, and to craft an exotic ear/ring/pendant it costs about 2g if you buy all your mats, so you need about 10g, which you would have in 7 days of dungeon running, which you would have done anyway for the other pieces of gear).
