Slick Slider Slows Down the Page Load

Hello, I have a site where I use a slick slider in the main page, however it adds around 1.2 second loading time . Whenever I disable the slider functions in works fine. so if that slider function works after loading the page I believe it is going to be allright. It is very small project for someone who is good at this. I also have a small css/html problem that needs to be solved. - People who did not read the requirements, please don't bid . - Workarounds, hacky solutions won't be accepted, (if logical, I can accept) I am a developer too, even if it is working, if I don't like I will have to cancel. Budget : 10-40£
