Troubleshooting help w/Wordpress Site

I'm needing technical help troubleshooting last-minute issues with our website before the formal launch. The site is www.rethinkstudio.org. It's a Wordpress site using Visual Composer. Here's a list of some of the open issues: 1. Mobile version gives us multiple columns similar to desktop site. 2. Images using Fast Galleries (necessary because of compatibility w/Visual Composer and with CDN using W3 Total Cache) stack on top of each other in certain situations to do with Tab and Tour objects. Other similar Tab/Tour issues as well (cut offs, etc) 3. General optimization of the site. Using BWM for Minification (because W3 doesn't work with minification). I'm looking for someone to work with me to trouble shoot these issues quickly and staying in contact in real time via Facebook IM or some other IM. Good English language skills are very therefore important. Once we have these solved, there are a number of other future projects to work on, such as moving the site to a new hosting facility. But these issues that I've outlined are most urgent.
