My marketing agency has a free guide that will walk you through how to create a marketing strategy for a product or service. You can access it here: https://www.facebook.com/bloominari/app/307339332686535/?ref=page_internal

I also recently published a blog post regarding marketing strategies for new products, and maybe that can help you, too: http://www.bloominari.com/blog/good-marketing-strategy-for-new-product

Please let me know if you have other questions or need any help with executing strategies.
