Mother's help duties and pay

[cookingfat]

I'm thinking of contacting someone who advertises as a babysitter to see if they'd be interested in working as a mother's help. Can you think of any other additional to babysitting duties that it would be reasonable to expect a MH to do (excluding cleaning - wouldn't expect this):
Ironing
Hoovering
Shopping - stuff I've forgotten from Sainsbury's

The ad is £5 hour for babysitting. Should it be increased for the above? (Not all every time, just to supplement babysitting, sessions of 2 hours).

Babysitting is in the evening usually. Mothers Help is daytime. Are they advertising for daytime work?

depending on the age isn't five pounds per hour below the minimum wage. If you expect babysitting, shopping, hoovering, and ironing you should be paying more than five pounds an hour. The five pounds for the babysitting is just for watching the child, so if you add in other things you need to pay extra for this.

Mothers help around £6-7 per hour. How many hours do you want her etc.

I'd definitely pay more - that isn't the issue. I was a bit shocked at the rate she's offering, as I thought just babysitting would be £7ph.
Anyway, can't contact her anyway, as childcare.co,uk charge £20 for monthly membership, and that seems a tad excessive for one email!
