Job Description

I need help with fixing the Google Analytics code placement for the site. The developer that I hired to built a site, added this functionality to the admin panel but once I changed the code it doesn't work.
I also need to have a banner placed on the site. I want this to be added as a functionality to the admin panel so I can change banners from time to time.
The website was created using Codeigniter.
I need this to be complete within 24 hours from accepting the job.
