Develop a Corporate Identity

I am launching a new digital side to my Australian bricks and mortar retail store, and I want a well-suited and well-thought out digital brand and a brand story to become the key to my success, as well as the centre of my digital strategy. What I want is the digital brand to be consistent across all platforms, and be suitable for all platforms. I want this to become my new corporate identity, and you must provide me with a great design that will work on my: Website homepage Website Landing page & Sales funnel Facebook profile & company page Twitter profile & company page LinkedIn profile & company page YouTube profile & company page Instagram profile & company page Google+ profile & company page Pinterest profile & company page The same design has to be able to be used on all paid digital (or print) ads in the future. Naturally this work will be responsive and has to work on phones, tablets, laptops and desktops. Please contact me for more information, and a link to my current website. As a last word, I DO NOT WANT anything complicated. Consider the 'f' for Facebook. That is all it takes for anyone to think of Facebook these days and it is that 'f' that Facebook has built their brand around. There is nothing significantly different about Australia and whilst this company is based in Australia and over the next 12 months will be only operating here, we also intend to be offering our product in Asia, Europe and the US & Canada in the next 12-24 months. I do not care whether you submit to me a letter, a word, a picture, a logo, a slogan, or a completely different or original design, it just has to be SIMPLE. Anything more complicated than 'f' is not needed. Thank you. My maximum budget is AUD$250 and below.
