I need help to adjust the colors

Hi,
is there someone who can help me adjust the Capulus template to my needs?
My site: fromusbyus.com .

What I would like is this:
The Icon find top left with: a Search bar

The phone on the top right with a custom menu module

The menu background with green color: #a1c31a

The sidebar button color from blue to Grey: #444444
The background of the template white instead of the pinkish color.
