Need Brooklyn Wordpress Theme 'HERO' Slider to be responsive for Mobile Devices

I am a web designer for [login to view URL], I currently purchased a theme that was said to be fully responsive and ready for mobile, however, it is fine except for my home page 'HERO' slider. This is a 'fancy slider' that works great on desktop, but does not responsively scale my background images or slides properly on mobile. On mobile OS (iphone and ipad from what I've tested so far), my backgrounds in the homepage slider get cropped. The main slider I need to be made responsive, is the first full-screen slider section of the site. I need someone to make the slider responsive and properly function on Mobile platforms so slides scale proper. The main issue, is that all of the logos underneath the quadcopter get cropped, and this is very important for clients to have visible in mobile (even if they get scaled WAY down from responsive functionality, it has to properly scale and not be cropped at the end of the day).
