PHP MySQL CMS E-Commerce Discussion forum Instant Chat

We would like a quote and time frame for developing a website in php / mysql. We will provide the html template page (which is ready to go) and we will also do any design work on the site. The site will include: · A CMS – the administrator will need to be able to create pages, sub pages and sub sub pages. · Ideally, the CMS would also include a HTML editor to allow the user to upload images, tables, PDF files, insert tables, links, etc… we currently use FCKEditor so this could be used if you cannot recommend a CMS that already includes a HTML editor with similar functionality. · The CMS will also need to include a facility to allow the administrator to perform URL renaming on the pages for search engine optimisation. Ex: [login to view URL] as opposed to something like [login to view URL] · E-commerce section to allow the administrator the facility to upload product categories, sub categories and the product details and images, etc... · Credit Card Payment Integration · instant chat (chat with a sales rep) facility · discussion forum · SSL The CMS, E-commerce facility, instant chat and discussion forum should all be based on code that's already available (in other words we don't want you re-inventing the wheel) and that we can re-use in the future. Perhaps you can recommend some readily available packages or code that you have used before. This site will also require a bespoke section that matches customer requirements against a number of columns in a database, not rocket science but there's a few extra days work in it anyway. The queries will probably have to be modified a few times to get the results that the client will need.
