Move logo and increase header image size

Hi, I’m creating a website on behalf of a friend and am pretty much a complete beginner…! Could anyone help me with the following changes in the Gateway theme please?:

My friend wants the business logo to show on the left of the page – is it possible to do this?
He also wants the header inage to be larger – again, is this possible?

We have purchased the Gateway Plus version of the theme, any help is much appreciated
