I have used Reference USA and Business Decision to market programs before with little success.
However, several small business entrepreneurs have been delighted by these tools and seemed eager to use them to market their small businesses.
Here is the flyer I created using Canva. I did not find it very user friendly,but I can see that it has its uses once you have created something a few times. You could use it to put up a very professional looking sign at the last minute to announce change of venue. I wish I had known about it when I was designing the Cats need new home flyer for my friend. oh, well.
