I need a Squarespace specialist to customise homepage

I need a a squarespace specialist to create the following.

1. A modern mac desktop background, copying the layout and theme style as much as possible this includes the header bar/toolbar/background/folder icon.

2. Use the mountain background, the toolbar at the bottom will look the same as the Apple Mac toolbar but will have the social media links, along with a mail icon that would open to a pop-up form for mailing list sign-up.

3. There will be about 20 scattered clickable folder icons on the page which will have a folder name under the folder icon.

3a. About 15 of the folder icons when clicked will take user to an Error page. Which will say ‘Error code 420, please try again.’ Each page should have a return/back button that says return to desktop

3b. 1 of the folders out of the 20 when clicked will have a link to sound cloud and a picture

3c. The remaining 4 folders will have separate videos on each page embedded from youtube. It will also say ‘not quite there, try again’

4. There will also be the Apple Mac HD icon on the top right corner. Which will either link to an external link or a sign up form for mailing list.

5. The site should be mobile responsive.

Thanks
