Does anyone have any experience with making Media Kits. I need a one pager or a flyer to use for a shopping complex that I own the domain name and want to sell advertising space on a website.
Media kits aren't the same thing as a one pager or a flyer. What you're basically asking for is called a "fact sheet." However it sounds like what you really need is an advertising kit. You can do that yourself easily enough. Just lay out your traffic stats, ad formats, rates, and terms. If you want it to be more visually appealing, hire a graphic designer to spruce it up a bit.
