Tech Company Homepage Design - Mockup included

RoundHouse

We are a tech company that provides cloud-based server support for web applications. We primarily focus on supporting Ruby on Rails applications. See our mockup

About Our name:
http://en.wikipedia.org/wiki/Roundhouse

"A roundhouse is a building used by railroads for servicing locomotives." Except we are servicing servers, not trains. It has nothing to do with houses.

Here are some of our competitors that have designs that we like:
http://railsmachine.com/
http://www.engineyard.com/
http://heroku.com/
http://www.hostingrails.com/

(We'd like to stay away from using much red. Only a splash at most)

We are looking for only the homepage design.

We want to be understood to be reliable and stable, but also very forward-thinking and cutting-edge. We are primarily business-to-business, but service is our number one mission, so an air of openness and accessibility is important.

Here is a list of sites that have the general feel/design I'm looking for:
http://www.silverbackapp.com/
http://www.panic.com/coda/
http://www.talktogary.co.uk/
http://www.veboolabs.com/
http://gottagettofowa.com/
http://www.alexcohaniuc.com/

Notice that the navigation on all these are very unique. Not just a list or normal tabs.

The Mockup:
I've attached a mockup of the content that CAN go on the site. This is to give you an IDEA of what kind of callouts, text areas, buttons, etc we need to support. This is almost entirely a marketing site, so a typical variety of content blocks are needed.

The mockup DOES NOT DICTATE the POSITION, FONT, BORDERS, etc of the page. That is entirely up to you! I am flexible with what goes on the page and where. The whole goal of the site is to give the visitor information about what we do and lead them to another page for signup & more information. The exact copy is also very flexible, so PLEASE FEEL FREE TO PLAY.

Style:
I'm looking for a bright, vibrant design that is very fluid without many hard lines. The more modern, artistic, and abstract: the better. Rounded corners as appropriate and other web 2.0 style things. The fonts should primarily be sans-serif. No comic-sans or similar.

The nav bar especially I'm looking for big bold buttons/links there (with icons maybe?). They can take up as much room as needed.

Color-wise:
I've attached our logo in two different color schemes. Feel free to use whichever fits better with the rest of your design. You can use these colors as jumping off points, but feel free to add additional bright colors (blue, green, orange, purple). The background of the site should be predominantly white.
