Switching Themes???

I am currently using Pagelines Platform theme and I am running into a cluttering problem with the primary menu at the nav bar. I am restricted to 3 menus and their is empty space to the left so some CSS modifications could solve the problem, but I would have to hire someone. That is not necessarily a problem as long as they know what they are doing so I would have to make sure of that.
On the other hand I could try another theme but changing themes at this point would be a complete disaster. I have custom sidebars with widgets and s sub domain for my blog. I have looked into the Pro version and it does not seem to have anything that could solve my problem just a lot of stuff I would not use. Any ideas on plugins pd or free for custom menus and I have that plugin but it is not going to work for what i want. I like my theme and I want to keep it i’m use t the layout and everything. https://www.webhostingreviewinnovations.com
