Case Study

Marketing website for video edit training startup

LevelUp Media Training's website is used to promote their video editing training courses.

The site is relatively simple - using 4-5 page templates. It was developed in WordPress with scroll animations which give the site visual interest.

What my clients say about me

John worked quickly to produce our new website. After our initial discussions he knew exactly what style we were aiming for and delivered it. We get loads of compliments about the site. We will definitely come back to him as the business grows.
