Change the skinning of a simple web app

I have a simple web app created for a client, with that client's branding. Now I need to supply the same app to a second client, in an almost identical way except that the branding is different (logo, color scheme, fonts, etc) You will receive the PSDs of the new design and will simply need to modify the existing CSS that will correspond to the new look. The current CSS file and images will be shared with you in a shared Dropbox directory, and any changes you make will update within 2 seconds on the staging site so that you can see the effect on the entire web app. You will not need to touch any of the HTML/JS. IMPORTANT: When you bid on this project please include in the PMB answers to all of the following questions (otherwise your bid will be marked as spam) 1. are you able to start working immediately? if not, when? 2. how many hours can you work over the next 7 days? 3. what is a direct link to the most impressive website for which you did the cutting from PSD to CSS and images?
