I developed a short survey to understand how people think about creating a digital business or product, using their knowledge and skills. It has to be short and straight to the point. 1) I need to check if the survey I created will reflect the idea research I'm looking for. 2) Where I can post it online to get replies (I already shared it with my network and friends and intending to run a Facebook Ad). Are there any other options?
If you're willing to pay 25 cents per person, you can try Amazon's Mechanical Turk: https://www.mturk.com/mturk/welcome
Here's an article about its successful use for surveys:
I agree with the Mturk idea.
You can also consider giving away the product once the survey has been filled. YOu can also directly add it to as a 'Thank You' pagee after your opt-in. Once a user says yes/agrees you will find it easier to simply ask. The survey naturally has to be quick, benefit driven and a reward attached.
