For something like that you need a CMS.
Just start off with a blog template (you can find hundreds of thousands out there....try this thread ::
http://www.freewebsitetemplates.com/...ad.php?p=30807) and tweak it to suit your needs. (If you need help, come to my web design site and drop me a line.)(Free to an extent)
Once you have completed doing that you will need a webhost that can support your CMS.....and again you are in luck, I supply 100% Free Hosting too.....
