Shopify Store Setup for Personalized Songs

I'm building a gifting-based Shopify store to sell personalized songs. I need assistance with linking a "Get Your Song" button to a popup form and redirecting customers to a product purchase page post-submission in a smooth, user-friendly manner on the Shopify Dawn theme.

Requirements:
- Create a popup form to collect:
- Recipient’s name
- Occasion
- Mood
- Ensure form submission redirects to the correct product purchase/payment page.

Ideal Skills and Experience:
- Proficiency in Shopify and Dawn theme customization
- Experience with form integration and redirection
- Strong understanding of user experience and design principles
