Joomla XML component required

I need a Joomla component that will display in a clearly understandable format the results of an XML feed in the front end for my clients. The data I require is password protected so I need a system that will allow me to out my username and password in and automatically update the xml feed on a daily/weekly basis. I need the component to link with "community builder" where it will use the "post code" of my client to produce the correct data from the XML feed in a tab in the front end or even inside an article. The information will consist of: Nearest doctors surgery Nearest Hospital Nearest Dentist Nearest Pharmacy etc: I have access to all the information direct from the NHS or please check out their website [login to view URL] and have a look at their online search facility, if you can figure our an easier way for me to get the information to my clients based on that system then that would be equally as useful. I am looking to work with someone with good communication skills, I have lots of projects I am working on besides this and if we find the right programmer we will continue to feed you work. I have attached a document that will explain the type of information available and how it works.
