Kubelanace script customization

We have a website built on the cakephp framework and we need to improve it some more. We need to add a few more things to it, like a cms for posting news and announcements on the site, adding a few new module positions and fixing one or two bugs. I'm guessing the cms part will be the most difficult to create... The most important part about this project is that it needs to get done fast and professional. The whole website cost us about $3500 and we can pay up to $1000 more if you can make the changes really fast. We want to hire a professional that will make this project his/her main priority - we'll get a quick result and you will get some quick money. Thanks for reading, contact me if you need more info.
