adwords specialist + small change on the landing page

This is really a small thing. There just have to be changed some pictures on an existing landing page and the logo there. This page is placed in adwords already and is working fine. So maybe you can bring in some of your thoughts to it and analyze the marketing page so far. And also set up all tools and html codes with google analytics etc. So I am just looking for someone who will have a closer look on my adwords campaign so maybe the ROI can be boosted after that even more + plus the small change on the pictures/logo -> only changing some images.
