complete a website me

We have created a site that needs a back end created, so that content can be updated by users. It's a very basic site that on some of the pages also needs rollover or click able information pop-ups with info, that in turn links to another page and gives the full information. All the content is ready but it needs the these simple functions that we don't know how to create effectively. Please let me know if you can do this by bidding and letting me know how much you would charge? A BIT MORE INFO: There are about 6 pages ( each a directory) that will need these rollover popups added to around 150 jobs. We will then need a back end so that we can add similar table content to the directory as the site grows. I will be able to show you a couple of examples of the site if this is a job you are interested in. Regards, Algie
