Build a Website

Hi, I am looking to create a new website for my artwork. I'd like to base the design on this website: [login to view URL] but add the following functionalities: 1. create a landing page where one static image will be shown 2. once in the grid of images, you can click on any image and then scroll through other images by flicking right or left, essentially zooming into the grid. 3. by clicking on any of the enlarged images as you scroll, you will be returned to the zoomed out grid of all images. 4. this must look good on a desktop and on a handheld mobile device. 5. I need to be able to easily change the order of the images displayed in the grid, and update the images in general. I have a total of 204 images, but will need the capacity to easily add more images. I will have a contact page and a CV page, as in the website above. Please do not hesitate to contact me with any questions or for any clarifications. Thank you!!
