Create a Wordpress Template

Hi, We are a real estate company with a wordpress website, we are having lots of issues with our site as it is not running smoothly. It takes very long to load properly and the responsive part does not work well on mobile phones. ***Please be sure to check the website in both your phone and pc*** We are looking for an “expert eye” to help us diagnose all the problems in our website and help us build a document with the list of specifications and requirements needed to be fixed, changed or implemented, list of recommended plugins to be installed, etc. So we can launch a freelancer project to implement these changes. The deliverable should be a document listing all the changes needed with a high level of detail so we can have a website loading correctly and fast. The website is: [login to view URL] - The website is in Spanish.
