How to start a nanny business
Get a list of prospective nannies.
Advertise in newspapers, online ads, put signs up, and give flyers. If you have experience in child care, solicit coworkers and contacts to see if they are interested in providing nanny service or if they know others who would.
Also keep in mind if someone does not want a flyer they are not interested so don't bug them they might spread the word, ruining your business. Do a thorough background check on each candidate.
