Hello Need a quick change of my ruby app template and also add new logo. This is a quickie task, I have ready coded css template. All u have to do is just intergrate it to the app. Winner has to begin the task asap as this is an urgent request. The app is a simple search music app that redirects results to hosting site. So basically like a googl or yaho search kind of app.I am estimating that its a 3-4hr task so i need u to begin asap and sticking within the timeline if possible would be great! thnx
