IT Consultancy Website Requires New Copy

We require revised and improved copy for an existing consulting company which already has a website.

There is existing / extensive copy already included in the website some of which is very technical. We require the new copy to be technical in nature but to be understood by the intended audience who are mid level managers looking for new service and solution providers. These managers have little time to read extensive content on a consulting companies website so we want them to get a feel for a company who are experienced, have a range of services and solutions to offer and that they should call us to find out more.
The existing copy can be revised or reproduced but the final result should be copy, which sounds believable, honest, serious and professional.
The required sections include:

Home Page:
Welcome copy indicating our key strengths on custom software development.
Our approach, which is collaborative
