Help with first Mod - Custom Career

[Emma123]

Hello fellow Simmers, 

this is the first time ever I have made a mod or 'programmed' (guess you can't really call it that way though). I used neia's create a career tool. However, there were two things I would like to add to the career that I couldn't figure out so far. I'm sorry if this is something very obvious but I've searched everywhere and can't find any solution, tutorial or anyone who might have asked these questions before me and don't quite know where to start if it's part or a subsection of some very general tutorial and I just haven't found it. 

1. I would like to add rewards, like bonuses or gifts for promotions.
2. I would like to add daily tasks.

Does anyone have any ideas or can anyone maybe point me to the right tutorial or even programme?
Thank you so much for your help (and patience  ) in advance.
