Self employed around school hours?

[Derbybound2022]

Is there anyone on here that works between school hours only, self employed? Ideally working from home? This is what I can feasibly do at this point in my life but I can't think what to do! I could also do a bit more with after children go to sleep at night.

What can you do?

Domestic work ie cleaning, ironing etc
Delivering parcels maybe? Amazon or similar

Dog walking.

Nails and beauty

Childminder

Virtual assistant

I used to but it was Consultancy work so I was paid by the day (a day being 7 hours) so when the DC were small I would only take on half as much work so I could spread the hours over 2 days and still do school runs etc. If I had F2F meetings I would arrange them around 11 and only relatively local so I could do the school run as well.

My friend is a software developer - she only takes short term (<3 month) contracts and never works school holidays. But her term time schedule is 8-6 wfh to allow for drop offs.

I still have one child not at school but does nursery a few mornings a week.
I have a lot of skills but have had a long career break. I am wondering if there are any profitable franchises I could run from home, for example. Or any kind of piece meal office or client service work that is remote wfh.
