Assistance with Codeigniter classifieds oriented website

I'd like to develop a Codeigniter website, classifieds oriented, with an expert guidance. I need workflow guidance and hands on php/mysql coding help from a professional. I have expert HTML/CSS knowledge and solid foundations on PHP and MySQL. jQuery will be used to implement plugins, but nothing too extensive Parts of the website (or a web-app) are: Back End Free Classifieds - name, description, adress, photo of the ad - anonymous and registered users can publish Facebook login Users database Newsletter RSS feed News CMS And bits and pieces I might need along the way. So, our collaboration would possibly work like this: I'll blueprint the application, then send it for review. Then code the database and php with constant monitoring and error checking. If something's really above my head, you'd code it and explain it. So my goal is to learn by producing with your assistance. Even though I'll try to take as little of your time as possible, patience is mandatory.
