I have two business ideas but I am having trouble trying to find out where do you go to find out market trends to know if there is a market for your business idea. Does anyone know where I should be looking for market trends?

Here are my ideas that I need to know if there is a market for it to work?

#1. Audiobooks (podcast) for kids..to assist and encourage early readers..age 4 - 8 years old. I would record early reader books and make the audio available for download in mp3 format or by order by CD. This one I would need to make sure that recording will not violate some copyright law.

#2. Publish creative solutions that small businesses owners can use to work smarter by saving time or money...


Let me know what you think about these ideas..and is there a market for these ideas?
