Build a Website

I am designing a website for an auctioneer to post his auctions. I am having problems adding the CMS. It will be a simple CMS, just 4 update-able pieces. The auctioneer (admin) must be able to access an admin page, add a new auction page as he gets set to have another auction, and add content to the new page (the new auction). Basically, for each new auction, he needs to add the following information: 1) (Calendar) date of the Auction. (This date will also appear on the main page menu "upcoming auctions"). 2) Gallery of Photos - pics of the items to be sold at the auction. He should be able to upload en-masse - multiple -file selection. The pics should be reduced in size, as thumbnails, so when you click on them, they expand. (I can do this thumbnail function myself, but if you can do it without any trouble, that will make it easier for me.) 3) Text block (description of items at the auction) 4) Clickable street address - which will lead to Google Map opening up. Also, the admin guy should be able to delete old pages (auctions) after the auction has been held. These guys are computer-shy, so this interface has to be very straightforward and simple for them to use. Thanks for looking!
