Simple Ads

I’m not exactly sure how to search for what I want, so I’m posting in hopes someone can point me in the right direction. I want to ad ads to a site. Basically we’re selling the ads to local businesses and they will just be their logo. I made a space on my site for them to appear one-at-a-time, probably as a slideshow to cycle ever, say 2 seconds randomly. Am I best off using a custom slider or is there a good ad management plugin for this? If I can track number of clicks and impressions, that would be a nice bonus.
