Create a web browser for us -- 2

I want someone to create us a web browser this will be our brand and it will work with our website and will be used by primarily our userbase. I think looking at what is out there I am happy to use the free open source rendering engines by Mozilla and the JavaScript engine that Mozilla use also(Gecko and Spidermonkey). If you want to use other please let us know we are open to new idea also. We want all the regular functions of a what currently Firefox has right now as it uses the same engine if that's possible. We may be shipping these out to our users on a disc so we would need something that is installable by a download file through our website and also an executable file that installs via a disc. If there is any questions please let us know. :-)
