We have an enterprise app that we would like to take from a layered PSD to CSS. It's very important that the code we generate is clean, fast and minimal.
We'd like to employ a framework like Bootstrap 3 or Intuit and use LESS or SASS.
OOCSS is also preferred, but not an absolute requirement.
I'm also open to fixed price vs. hourly. We can negotiate. I have included a sample of our app in the attachments.
