Optimize Webpage Load Time (javascript, image loading, etc.) NEED ASAP

I am looking for someone who can help improve page load times. Currently, we have optimized our image files but are still facing some long site load times according to [login to view URL] and running Load time analyzers locally. About ~6.5seconds (target <4seconds). We need someone who is familiar to examine what might be causing the long load time as there seems to be multiple connections to single objects. Need someone ASAP (will be up for several more hours to try and debug this issue). Experts only. Only respond with '***' in front of message so I know you are not a bot. Thanks!
