Nest Brother We Manufacture smart innovated home products, from appliances to composite building material. We are inspired by birds in the way how they build their nest. That is why we name our company nest. In addition we are three brother and that is way we want to brand our company as NestBrother as one word . We want an inspiring logo that focus to represent three brothers which reflect in every worker and employee in our company. What we are looking for is : Full package of printable Brand identity with a Simple Logo, elegant, professional with a tagline of "WhatCould". What we mean of "WhatCould" is that we want to product to make people’s life better not in the way of what should be done as a traditional or conventional way, but rather of what our houses " COULD" be built in a way by adapting the designs and the way of building from nature. In that case we are referring the bird’s technique in how they build and live in their nest. Please look to the suggested logo attached for you to have an idea where to start from. And make the necessary modification that is needed to make the Logo more professional that translate the company identity. I want the look of the logo to be eye catching, professional, and simple like Apple computer's Logo, or as attached sample image that I've sent. Note, the samples in the attached files are not necessarily representing the log I want; it is just to show you the colors and style I like to see in my custom logo design. But the PSD File contains the original old Logo of my company which I want it to be modified to whatever necessary style to make it more pro.
