I have has a go on the search engine but couldn't find much up to date...
I have been a nanny myself, and now work for an agency, but I have never had any dealings with aupairs before! I know several people in real life who have aupairs... but IMO don't treat them as they should :( with regards to both salary and duties. The most obvious one who springs to mind, pays her AP £45 a week and her duites are more like a full time nanny....
I am thinking about having an AP come and stay with us as I work from home most of the time (any time when I have meetings I can leave DS2 with my mum/friend) and think this would make me so much more efficient... and less guilty for using the cbeebies babysitter for an hour a day... 
I am looking on AP world... but they suggest 140-170 pounds per month.... that sounds much lower than (common sense) and people on here suggest?
The role I am looking at is not a difficult one by any means I don't think...
AP will not be required to get up and help in the mornings. I will drive chidren to school.(DS1 full time, DS2 3 mornings per week). I would just need her to entertain DS 2 in the other rooms whilst I work for 2 hours or so in the afternoon. (nothing too difficult, playing with toys, reading, drawing, maybe go across the road to the little woods, etc). Later on in the day I would like some help with either keeping an eye on/ playing with DS2 whilst I help DS1 with homework, or vice versa. Reading with DS2 in the evening. Tidying up downstairs after dinner whilst I get the boys ready for bed/bath etc. Hoovering and the odd bit of tidying. No laundry, except maybe putting folded clothes away into the drawers. I have mentioned one nights babysitting, I doubt we will use it often, but I'd like it mentioned so it is available if I want it. No school runs. No sole charge, or maybe only very occasionally- and not of the little one for any length of time. Really it is the sort of stuff that I would be happy asking my 17 year old babysitter to do (actually I'd leave her happily in sole charge because she is wonderful!! But you know what I mean!)
I found someone who I thought ticked all the boxes... but she asked for £550pcm!! 
She said that is what her friend gets... I am pretty sure she is trying it on, sadly. I am not prepared, or able to, pay that sort of ammount. I was thinking more in the region of £75pw. Does that sound ok?
What do you pay, and what sort of role does your AP take?
Thanks
