How to make a babysitting ad?

You could make ads on a 'Craigslist' website, or on poles around supermarkets near you. Put on there your name, contact information, what your purpose is (to babysit), how much pay is required, let them know if you will babysit in your home of theirs, email address(?) - optional, include age, age of kids that you want to babysit for, how many children/babies at a time, a little of what you'll be doing while babysitting, and if they have to include meals or if you provide snacks/meals.
