Question
I'm not trained to do this myself, and I don't have the time. I want to pay a commission to someone to do it for me. Let's assume I'm right that this is a great product that will sell. How do I find, and vet, a legitimate marketing company or expert who will pursue this?
Answer
You should reconsider your needs. If you're making this product, no one besides yourself can market it and sell it better than you. After you get 10 paying customers can you recruit or vet the right sales person.
