Tl;dr- I want to open a home daycare in San Diego (HCOL) but it is VERY expensive to do. Is it worth it?

After much research of how much the rent would cost for a decent and qualified house/condo etc. in a decent area, plus the cost of hiring workers, even at minimum wage, plus the initial costs of buying all the necessary furniture, supplies, toys, etc…it’s veryyyy expensive. Between rent and paying other workers alone, I would need to make around at LEAST $12,250 a month. And since this would be my only source of income and you can have up to 8 children (depending on ages) that would mean each family would need to pay about $1500. Possibly, and most likely, more, because the rent that I factored in is the cheapest that I found. That’s if I could even get 8 kids. Would it even be worth it to try to pursue this? Thoughts/tips/advice?
