Website & E-Commerce- Developer- Merch & music store

I’m looking for an experienced website developer to help me set up my existing website to sell my merchandise and music directly to customers. I need someone who can create and set up an online store for my clothing/merch, including products, pricing, photos, sizes, checkout, and payment processing. I also need a system set up so customers can purchase and download my music directly from my website. The developer should make sure everything works properly on both mobile and desktop and provide guidance on the best e-commerce and digital-download setup. Please send examples of similar websites you have built.
