I want to replace the BusinessSolutions mast head to something else

I want to replace the BusinessSolutions (BusinessSolutions template) mast head across the whole site to something else, can someone please help me by letting me know the steps to take.

Hi,
If you want changes in "Header" :
Please find the following in html :

HTML:

<a href="index.html" id="logo"><img src="images/logo.jpg" alt="LOGO" /></a>

To change this, create/replace new logo file with name logo.jpg and upload it into "images" folder. So, It will start reflecting a new logo specifically.

If you want to change color of "background" of header then you can do that with, following steps:

Find in "style.css" :

Code:

#header {
    width: 960px;
    margin: 0 auto;
    padding: 40px 0;
    position: relative;
}

New added with background color :

Code:

#header {
    width: 960px;
    margin: 0 auto;
    padding: 40px 0;
    background-color: #F5F5DC;
    position: relative;
}
