Need a landing page with about 4 sections that will introduce my first three products for a new all natural organic skincare line I am developing. This is to not only introduce the new company products but to get people who will support me in crowdfunding campaign and who may believe in the product. These items should be highlighted in the page Environmental sustainability, carbon footprint, 100% Natural, Vegan, as well as cruelty free, I want these products to show that it is greatest skincare solutions ever. Functionality would be a sign up form ,a call to action where people can sign up to Free samples, Free Giveaways, newsletters , include a blog section, social proof, I will have a video to add, mobile friendly, social media Icon, optimization. It needs to have a clear value proposition(explains what a product or service offers to a customer and how it's different from competitors).I used Hostinger as the host for my WordPress and eliminator .
