Simple Three-Page Site on Squarespace

I'm in need of a skilled web developer proficient in Squarespace to create a simple, three-page website for me. I have an exisiting site in squarespace that is similar so all the assets (fonts, colors, logos, images, etc) will already be loaded into/can be referenced from the current version of the site. I have already prepared the text copy. One thing that is not apparent from the mockup that I included is that I need a "we use cookies" warning to pop up the first time a user visits the site. Also, the contact us form should generated an email to us on the backend.
