Spead up our website, specifically the blog

Our blog is very slow, we need someone to look at the problem that causes it and fix it. Our provider is [login to view URL], so please only make an offer if you believe that you can fix it considering that [login to view URL] is a slow provider. Our blog used to load much faster and the rest of the website works fine, so I believe that this is fixable. The image of the blog loads fast, but the text appears a long time later. This is the website: [login to view URL] At the moment it takes anytime between 11 to 26 seconds to load the blog. We would like to have the blog (photo and text) load in less than 2 seconds. Also, our website speed is currently 10 on [login to view URL] We would like you to bring it up to 75+. This is the third time we try to work with people on Freelancer. If you are not absolutely certain you can deliver the results, please do not make a bit. We will only pay if both requirements are delivered. Please write "Read and understood" at the beginning of your offer, so that I know that you have read the description.
