I think your website is informative and straight forward but also comes across very dry. You don’t have any tabs for people to click on, so it’s continuous scrolling down until you get to the end of the page. You should add tabs so it looks like there is more variety and substance to your website when people go on it.
You really think people will buy an iPhone from aliexpress? That's a tad optimistic. Check your links too, the one I did click on had this: It looks awful, not sure why you've used WordPress for a single page site. The design looks like one of those old hard-sell get-rich-quick sites. Good on you for taking a punt on this market but I doubt it's going to work.
