Build a .Net 3.5 Website

I've got an HTML Website, i want to convert it to a .Net wesbite. at the moment the purpose of the website is only advertisment. but it may expand at a later stage that's the main reason i want it built in .net 3.5. the main page of the .net website will be the same as the [login to view URL], then i want a master page added (it should look slightly different to the main page) and all of the other pages will be web content pages that will inherit from the master page. also i want the services menu item to be able to expand and collapse to show its sub menu items. in the menu i want an item added (it doesn't exist now) called "Cleaning" and add the relevant web content page to it and leave it blank (i will add the text later on myself). Also on the main page of the html website ([login to view URL]) we have pictures in the body, i want them removed in the .net website and instead have one box that will contain a slideshow to display all the images. Also i want the contact us page to be able to send email after the user enters all information. attached is the html wesbite. many thanks
