Shopify Site Development for Digital Products

I'm looking to create a Shopify site focused on selling digital products. The project will involve:

- Setting up a new Shopify site tailored for digital product sales
- Assisting with the setup of all necessary features and plugins for digital product delivery
- Providing support for the setup of a specific payment gateway

I already have the PayPal gateway on another site, so I need help integrating that. The ideal freelancer for this project should have:

- Extensive experience with Shopify
- Knowledge of digital product e-commerce
- Proficiency in integrating PayPal with Shopify

Please let me know your experience and proposed timeline for this project.
