Big Blue Button(BBB) - White Labelling

We want someone who worked with Big Blue Button before to do fast white-labeling both for the system itself and for its Greenlight front end. We want to replace that with a different brand name. Such "customization" means none of the mentioned brand names or links will exist in the system after performing the customizations, which includes, AS AN EXAMPLE:

1. Remove Help Button
2. Remove About Client Button
3. Change Name in Browser Title <title>
4) Footer
5) The BBB startup document when you start the session
