Customize WIX Installation package and compile to MSI

The attached installation package provided to allow developers to customize the installation of some drivers needs to be modified, so that the installer displays our company information. The Drivers installation package was built with a free tool available from Microsoft® called the Windows® Installer XML (WiX) toolset. I have little experience with this and need it modified as quickly as possible. I believe it will just take changing the XML data to reflect our company and product. I'm hoping to choose someone today, that will hopefully be able to finish today as well. We're basically just changing the text displayed during the installation. I just don't have the time to figure out how to compile it all.
