Apocalypse Challenge Discussion Thread

Hi. I'm new to the Sims 4 Apocalypse challenge (and the Sims 4 in general). I stuck with Sims 3 for a long time! I'm also playing on console, if this matters.

I've finished the tutorial and have kept playing my tutorial Sim for a few more game weeks, but I'm itching to start another Apocalypse.

My first two questions are:

1) What's the best way to get a good founder on console version?
2) Could someone give me a better idea of starting an apocalypse than I have right now? I start on an empty lot, but with how much in funds? Wouldn't a good founder have way more funds than a CAS? I know I have to give up all funds as soon as the bills are due, but could I theoretically start with really high funds and build a good apocalypse house right away?

Other questions:

3) Any restrictions on nannies? I see no maids out of the gate, but what about nannies, repairmen and gardeners?
4) One stack of objects in personal inventory? Does this mean if I have a carp in my inventory, I can't get a goldfish? Or does this mean that I can't have more than one stack of each type of fish?
