I have read your project description, and i understand what you need. Only thing that isn't clear from the description is, if you need also re-design your website a bit. Adding the sidebar isn't problem at all, but i'm not a designer, so if you have some extensive graphic changes, don't consider me as your choice. On the other hand i have strong knowledge of Wordpress, PHP&MySQL, HTML&CSS, and JavaScript, and over 10 years of experience in web development, so i can easily make this project done for you. If you have any more information, or any question, please don't hesitate to post them by private message, thanks.
