a website is a good idea. I use weebly.com It is so easy. My 60 year old mother who is horrible with computers was able to put a website together on it. its point, click, type. It has a free version (which I use) and a paid upgrade if you want. with the website you can put as much or as little in it as you want. S depending on what you want on it, depends on how much time you work on it. I spend a lot of time on mine, but i fine working on it relaxing.
business cards are good to have. make you look more professional. (vista print.ca is a good place to get them) they also have lawn, widow, car signs. I am thinking about getting one of there hooded sweat shirts with my daycare's name on it and a hat.
