Create an amazing CSS for our Web App

Hello designers, we are looking for someone who is SUPER creative and talented in CSS (we use Bootstrap in our App). We have developed this amazing application which you can view here: [login to view URL] Login: pass: 123123 So login and check it out... Now, we are looking for a CSS designer to create two themes for us. 1. A light theme (which is what it is now) but would like to enhance it, make it even slicker looking, cleaner 2. A dark theme (kind of like Photoshop CS) Now, you can ONLY EDIT CSS file... you can't modify any HTML (can't edit [login to view URL]) or JavaScript. So, if you run into a situation that you need to edit something in HTML or something we do in JS, let us know and we will expose it via a class so you can access it in CSS. Feel freee to change icons (we use Font Awesome and Bootstrap, so pick between these two libraries), colors, dimensions, surprise us... make look awesome. If you get the job, you can get the entire application from [login to view URL] and host on your own web site (follow instruction on github and so make sure dir is same on your server), and once you are ready, share with us only the CSS file so we can see what you did (again just edit the [login to view URL], nothing else). Questions? let us know, Regards, Sean
