Next time you need start new thread as this thread is marked as resolved.
You will need make change in your child theme header.php
To put a logo in right hand, upload your logo using media.
click on logo and at bottom you will see url, add this url in bottom code where I have add image url here
in header php look for this code
</<?php echo $heading_tag; ?>> just after that add
<div style= "float: right;"><img src="Your image your url" width="100" height="100"></div>
this will put your logo on right above description I have example here adjust your logo size as you want in code.
In style.css look for this code
#branding img {
border-bottom:1px solid #000000;
border-top:4px solid #000000;
clear:both;
display:block;
Change top and bottom border 0px.
else you will have line at top and bottom of logo
