i have completed at least 10 odd jobs given by vex and delvin, 5 a piece, i'd say good mix of the options each member gives me. i see some slight improvements like carpet in the center, and 1 merchant already set up shop. this is getting tedious, how long before its completely upgraded ? also when and how do i get the thieves guild leader armor ?
From what I understand, you must do 5 jobs per hold, and once you do you'll get a special mission for that particular hold. Once you do the special mission for each hold, I believe the Guild is restored to full.

DO all the quests from Delvin and the other chick. Once you do 5 side jobs per city, besides Riften, you will get a special quest for that city. Do that for all the cities and you get to restore guild and you become guild master.
