Your idea is very well structured and I think you should have a big advantage because your team has already designed a product made of EVA. Have you had any negative experiences with the material at all? Especially the size of the target market has convinced me of your idea since the list of potential customers is virtually boundless. Combined with the powerful CSR strategies of multinational companies, your concept is very likely to thrive.
I think you have come up with a promising idea that could sustainably change the cityscape for good. With respect to your current stage of development, I would like to know if you have already tested your prototypes under different weather conditions to see how humidity and heat affect the material.
Good luck with your proposal and I really hope you will be announced as a Top Idea!
I truly believe you and your team have created an excellent idea that might be able to improve the lives of millions of people in the developing countries.
From your proposal, it becomes apparent that you have already begun with local marketing and sales activities. I would really appreciate hearing a little bit more about how this first stage of your plan went and if you were able to reach your set objectives.
