If you have a website, this is a good way for advertising.
You bid, on a price.
I have used it for my home business.
Also:
www.vistaprint.com for having ALL kinds of business things/advertising materials made. Good prices, nice products. I have used this too.
DO NOT, place fliers on doors of homes. I HATE when people do that... it is also an invasion of privacy. I DO NOT LIKE, 'strangers' coming up to my home/door, to place anything.
It is a turn-off.
NOR is it legal, to place things inside a person's mailbox. ONLY a Mailman, can do that.
Put fliers up at community bulletin boards/at Universities/Grocery stores etc. or community newspapers.
Also: advertise in your local, community websites.
or local Mommy groups.
