Electricity company suggestions for big family

Hi guys, I'm confused with comparing electricity rates and discounts and usage charges ahhh.
I'm located in blacktown NSW. I'm currently with Origin Energy, have been for a few years now. We don't have gas. We have a big family and our bill is huge. We have people home during the day and night.
According to the bill our average kwh is 35, and we spend $9 a day average on electricity. Our last bill for a 90 day period came to $800 roughly.
I have spent the last 2 hours on comparison websites only to be left confused as some have flat fees, some have discounts that end after a period of time, some have peak and off peak prices.
Please please can you recommend a company if you are in a similar situation?
