Make up artist website

Hi I'm looking to update my website. The website's pimary focus is to act as an online portfolio for my work. The priority is to have a site with 4 or 5 photo gallery pages. Ideally each of these galleries (special effects, fashion, prosthetics, miscellaeneous)should have a selection of thumbnails and one main picture. when the thumb nails are clicked on that image should then show (enlarged) as the main picture. If none are actively selected then the main picture should act as a slideshow of all of the thumbnails. There should also be a contact page where people can email me directly (no new address is necessary) and probably an introduction page. The photos that will be on there will need to change on a regular basis so ideally I would like to be able to do this myself. I already have hosting and a domain name. There should be no need to scroll down on any page. The site will primarily be viewed by Mac users although I am a pc user. People will only reach the site if I give them the adress so I am not worried about google ranking or anything like that. If you think you can help be I'd be really pleased to hear from you. Thanks Julie
