CMS system to be applied to site

Hi, I am looking for somebody to apply a CMS system to my existing website. The site has already been been built in dreamweaver using PHP and HTML. The site is a comparision shopping website and although payments are not dealt with directly, I understand it could be prone to getting hacked etc so require the security a CMS system brings. The person who accepts the job should be skilled in PHP development. The reason for this is that I require several features to be integrated into the CMS, which already exist on my site. A good example of the features I require can be found at [login to view URL] so please have a look at what is expected of you on there. The most important of these include: A "last viewed products" section which automatically tracks the last items a visitor has looked at A feature which can allow visitors to save products This job is also likely to be on-going, with several changes and tweaks along the way. I must also state that the person or company who receives this job must be very good at communicating due to the nature of the project and be available to talk about things on msn when I need to. I will need to upload all my website products to the CMS system using an excel spreadsheet so please keep this in mind. Once the CMS has been completed, it is likely I will require the same person for further development on the site so this could generate other jobs. Please ask if you require further details. Payment will be made on completion of the work.
