Shopify Subdomain Setup

I currently own a registered domain and I'm looking to create a subdomain specifically for a separate online store on Shopify. The store will have less than 50 products and I need someone to help me with the setup and connection with Shopify.

Key requirements:
- Create a subdomain under my existing registered domain
- Set up a Shopify store on this subdomain
- Ensure seamless integration between the main domain and the subdomain/Shopify store
- Configuration for less than 50 products

Ideal candidate should:
- Have experience with Shopify setup and customization
- Be proficient in DNS management and subdomain creation
- Demonstrate attention to detail to ensure a smooth user experience
- Provide recommendations or insights on best practice for setting up a subdomain for a small product catalog.

Please include examples of relevant projects in your bid.
