Joomla website add ads using ijoomla ad agency

Joomla website add ads using ijoomla ad agency. I have some very small ads on a website. I need to take a long one and instead ad 3 ads in there using ijoomla ad agency. We need to rotate a few of them (this is a simple click on the extension). We need it to work perfect! Thank you! P.S: Needs to be worked on right now not later. Should finish soon too.
