Only if you need a serious developer.
I have more than 9 years of experience in Web development, primarily in HTML5, CSS3, JavaScript, PHP and Wordpress and I can help you with your project. I can create a script for you which will let you stop a video by defining a time interval (like every 30 seconds) or an exact time (like 1:08:10) and it will work on your Wordpress site.
I have a lot of projects in my portfolio, make sure to check them out.
