Thing with jobs from buisness woman is kinda of a trap. Many would select her for good money, but that is not her real role in game, to provide you fast cash that is. Her role is to end in sexual relationship with her. That means that when you accept your first job from her, do not ask for money as a reward but go for second option (sexual one). Then you repeat same process with second job. That will open you acess for next, third job and continuation of story with her. Also, whenever you go to her I recommend to visit her at afternoon to have space for other activities in morning (talks with some of main characters such as sister, mom, aunt, Tom`s mom). Hope that helps youhow can i find the key for bussiness women third job?
please help
