I could use some Custom CSS to align the logo to the left (please add in a link to your site so that I can try doing this), however, to add the ad area, you’ll need to create a custom widget area.
The logo can be moved with a bit of CSS code. You can use the following CSS code to move the logo by going to Appearance > Customize > Additional CSS and pasting it there.
/*Move logo to the left*/
.navbar-header {
float: left;
}
