My boyfriend used to work in a playcentre/ preschool kindergarten in Hong Kong. Every country is different but he loved what he did and is amazing with children mine ,and my friend who home schools her children and asked when he could come back to entertain her kids.
What I suggest and what made me comfortable with him with my own children is reference letters. You have friends and families and I'm assuming you have watched other people children and been responsible in there development somehow.
Maybe they can write reference letters. Also a suggestion find some play group drop in centers maybe you can volunteer at, my current daycare my children attended to they have different people in at times gaining experience who are completing the e.c.e
I'd contact some providers grated you will need to provide a police clearance as I will be working in some daycares to gain experience before I open mine as well.
Personally I wouldn't have a problem but as someone who has been abused the red flags would click in for me.
If I was going to use you as a provider I would expect the following but this is just me.
Police clearance
Maybe something from child services saying your a fit person ( overprotective mom )
C.p.r for children
First aid
And something that give some formal training on daycare
Reference letters from parent of children's you have cared for or from a placement to gain exp.
I hope I have not offended you in anyway as being a male daycare provider. I have red flags as being abused as a child I wouldn't want to have my children go through that. That being said not every un related male would do that.
Just my words
Good luck
