I haven't started my own business yet. I've only been doing research on getting things started for about a week now. So use your own discretion for what I'm about to say.
I can't speak for what's in those kits, but after a quick glance I don't know what could be in them that isn't available for free on the internet with a little googling.
A quick YouTube search I found this channel /user/thejanitorialstore
While I haven't watched many of them I've used some of there videos before. When I started working for cleaning company my boss sent me some of these videos. They seemed to explain things pretty well. And it looks like they have some videos for the business side of things.
Have you been too sba.gov ? Assuming you're in the US they have a lot of info for starting a business.
There seems to be a lot of people on here who are helpful too. I would think between here, google and YouTube I think you'll do fine without those kits.
