Adapt Webdesign

We need a adaption of our webdesign.

Our website
https://www.firmenkontor24.com/

should be copied. We want to create a "sister"website.

The have to bee changed in firmenbonitaet24 - also we need a new color. At the moment with the color we aren't sure, so we need some ideas from you. At the moment we have one of the following colors in mind:

- blue
- orange
- red

Perhaps you've a better idea and convince us with a other color.


I expect:
- finding color / testing color and adapt color in logo, perhaps addapt buttons. adapt background-color to match new color, etc.
make it beautiful :)

I have from all the PSDs files.

Edit:
What i don't want is a complete new Website. It's just a adaption of this one. Just changing the color scheme.
