Help to Reduce Wordpress Website Speed

Hi, I'm looking for help with my website speed. I have a website that has quite a lot of content and needs a faster load time. I've tried caching plugins, I've tried image reducing plugins, but it isn't loading fast. I need someone to help with more complex methods (CSS, script calling, javascript) or whatever you feel needs to be done to make this website load quickly. Before I award this project to you, you have to provide an analysis of my website with a short description of how you will solve this problem. I've already run website speed tests, please do not just copy and paste speed-test results and use the suggested fixes as your analysis.
