WordPress Theme Tweaking

I need to work with someone who can refine this theme - ensuring the navigation is consistent and ensuring it works correctly.

For example - instead of the 'pink' colour - I would like to change to blue.

I already have the theme installed - and have made a start in the back end - so I'm just looking for someone to help me finish it off and ensure the nav - and the Google Map works correctly etc.

I will provide the theme to selected freelancer
