The option in the conversation thing just isn't there.Anyway, I have completed about 30 mini jobs for Vex and Delvin and also completed 4 of the special quests. The problem is that Brynjolf is always busy. No matter what I do I can't activate the Under New Management.
Also, I have collected all of Delvin's special items, but for some reason I can't sell him the model ship.

Does anyone know if this is fixable? I don't want to restart, just put in close to 65 hours of play and I really don't want to go through all that again!
P.S:

, hence why I can't activate the Under New M... Quest? I have a few merchants now in the guild Red Flaggon but one little den thing is empty, does this mean I'm missing a merchant
Thank guys,
Any help would be really errr... helpful

EDIT: The reason why the quest wasn't kicking in is because I didn't complete 5 mini jobs in Markarth. In case anyone searches for a similar problem and finds this thread I did this:
I checked through my previous completed quests to check how many I did in each city. If there are not done 5 times in each, you need to keep asking for more jobs to get there, then the quest should become active once ALL special jobs are concluded. You can cancel the mini jobs and request a new one until you find the applicable city.
