Bootstrap CSS design for on-line portal

General information for the website: On-line communications platform for vehicle owners
Kind of development: Customization of existing website
Num. of web pages/modules: 3-4
Description of requirements/features: We are building a new specialised on-line platform, with rather limited functionality and simple interface. We are using the (plain) Twitter Bootstrap framework for the user interface and need a theme / design to make it look nicer, better organised and easier to use. Design should be very clean, with a focus on usability.

Site should be fairly accessible (larger fonts, good amount of spacing, high colour contrast, clear labeling and flow) and responsive. Code should load fast - no fancy effects or large images.

I will provide the logo, which should provide a basis for the colour scheme and style.

Ideally, I want a CSS-only solution that works ON TOP of the already existing HTML and Bootstrap framework. We can make some changes to the HTML here and there to make your work easier, and we can move text and blocks around for better usability, but most of the main HTML structure and coding style should remain intact.

Your CSS code must be clean and easy to maintain. Keep in mind that the site is in its very early stages and will be changing / evolving significantly with time.

In your bid, please make it clear that you understand the requirements and are a good fit for the job. Generic proposals will be declined automatically.
Specific technologies required: Twitter Bootstrap, CSS
