Create a fast-loading slider for vBulletin CMS

Hello, I am looking for a freelancer to create a fast-loading slider for my website that uses vBulletin CMS. Currently, I have a slider on my website that is based on Nivo slider to show the featured articles. The problem is that the slider takes a while to load the images and the section that is reserved for the slider comes up blank for a few seconds. My website URL is www.Ndakaru.com. You can see when you go to the site that the box that says "A LA UNE" comes up grey for a few seconds until the first image is displayed. I would like to either modify this slider to load up images faster or use a different slider that does not show this delay.
