So part of the question you need to ask yourself is this. Are you in the financial position to help others? Do you have the time to volunteer and make jobs in your community? If so, this might be something good for you to do.
Personally, I have the time and money to make it happen, but I have a lot of experience with people, ie cleaners, and I know how they are. There is a reason that out of every 100 that go in to business each year, 98% of them go out of business within 6 months. Out of the 2% that is left, 99% of them go out of business within 5 years. This doesn't include all those that get 1 or 2 houses to clean and then call it quits after a few weeks.
So while there is always a new group coming in, my personal goal isn't to talk someone in to paying... for example $400... knowing they probably had to beg, borrow and steal to get that much... and within 6 months most will never have used what I teach them.
As for your $200 worth of supplies, again, my personal goal was to make it so people could make money without spending a lot of money. 5+ years worth of window cleaner + dispense system to get started is $25 (for them to refill is about $12 for another 5+ years). Shower cleaner $3 for 1 year supply (renew is about $2). Toilet cleaning supplies for 1 year $12 (renew is about $3). 100 Magic Erasers $7. Broom which doubles as a flat mop by changing heads $25. Vacuum $50. My caddy is $25 but plastic caddies can be bought for $2. Towels $20. A real cob webber that can reach 20+ft tall ceilings $30 depending on the pole a person would want to buy.
All of those prices except window cleaner are for 1 years worth and it might last longer than that. I said 5 years on the window cleaner but it is more likely to last a small company 10 years. A regular person could buy it once when they turn age 18 and be set for life.
If you're wanting to help people, that's the kinds of things you need to do. But with my experience of cleaners.... it's pretty much a waste of time to give them good help unless you just get bored and come here.
So what other kind of idea(s) do you have for me to rip apart?
Is that your goal, to make jobs in your community?
