Joomla Web Maintenance & Events Module

I'm having some issues with an existing Joomla Website that needs some maintenance. These issues are minor but you would need some experience with the Joomla events module. Also, there is a scrolling box on our main page that needs updating with some provided logo's and some cleaning up of formatting on one of the pages. We are a company based out of California. We would prefer the Freelancer to also be open to any future work as we need someone to help provide future support for our website.
