Add Fonts to Shopify Theme

Hello! I'm looking for a developer that is familiar with HTML, CSS, JavaScript, and Liquid. I'd like to add three fonts to my Shopify store but I lack the skill to do it. I'm using the "Flow" (https://themes.shopify.com/themes/flow/styles/byron) theme on Shopify so if you're familiar with it that would be even better. I'd like to add the Font Awesome icons to my navigation and make so that I can select an icon inside the editor for each navigation item. I'd also like to add the Seravek Basic font and the Aadhunik font to my website to be used anywhere I might have text.
