Customization of template

I need help with my wordpress site. Both for the woo-commerce Isotope grid that I want to have included ([login to view URL]) but also with site performance. I have recently purchased this template [login to view URL] and have started customizing it myself. However, I have reached my limitations to what I can actually do myself. For the site I need to have the following done: - In the designer overview I have inserted the portfolio overview (this is the nested isotope grid) - I want the same grid in the woo-commerce product overview, the related products and basically in all sites that has anything to do with woo-commerce product grid. - I want the sorting function to work as a dropdown (as it is now), but with the isotope sorting function in it. - The site is performing poorly and this should also be optimized. I have been running a performance test here: [login to view URL] Attached is some illustration of the current site and a walk through of the functions. Please let me know if additional information is needed.
