Wow! If someone will come in and cook, clean and tell my MIL to eff off when I've had enough, I'm defo very pro this idea. In fact, I'd prob like to hire one of those on a permanent basis, regardless of baby's arrival! 
One or two hours worth of help a day sounds good to me, especially as it means you won't have to worry about cooking decent meals or washing up! Any more time than that though, especially full time, I would hate. Those precious first days are so magical as a new family.
I don't know what it's like in the Netherlands but over here (nhs), you get released from hospital and in the baby's first eight days, you get visited by the mw three times - more if you call and ask them (like I did when I was struggling with breastfeeding on our first few days out of hospital, she came three times in one day, in fact!) They check any wounds, help with feeding issues, weigh bubs, answer any questions and then sign you over to the health visitors (I can't remember when the hv first comes but it's not on day nine or ten). Guess it'll be different there because you don't have an nhs?
