Move the logo from left to right

Hey, the logo in my site is on the left site. I have a search box on the same line of the logo but on the right site of the page. You can look in my site to see more clearly.
Now I want to move the logo from the left to the right and also move the search box from the right to the left. In short, I want to replace the logo and search box places.
How can I do that please, thanks ??
