Leaflet and content design

Information on the business: Software Company for Accountants
Industry: Technology
Design details: We are a software company who specialise in providing software for the accountancy sector. We are about to launch and as such, I require leaflets / brochures to be created.
You can visit our website www.capium.com to gain a perspective of what we do and potentially of what we require.
Ideally I am looking for a design which is folded in 3 parts of an A4 page (double sided) which is tailored to Accountants.

I'm happy to discuss further, however I hope the above is enough to gauge my requirements.
Target audience: Accountants
Content on the front/back side and body: Open to suggestions on the layout, however content can be gained from the website. I'm pretty open as you are the professionals
Ideas for the visual style: I'm open to suggestions, however please look at the website
Things to avoid: n/a
Preferred colors: similar to our website colours
Extra notes: I want the brochure to be very eye catching. It needs to be sales oriented and targeted to accountants
