Wordpress Web Developer

I am setting up a wordpress listing site using the base theme of ListingPro. I am looking for someone who is able to code and add to the theme making the site more suitable for my needs.
Examples of what Im looking for, general website design- making it look better with colour, arrangement of content, icons Upgrade to see actual infocorporating more on top of the theme, such as real time reviews from other websites such as google or trustpilot.

People signing in with their facebook account, leaving reviews with their facebook account.
and other things to optimise the site best for user experience.
