Minimalist E-commerce Site for Jigsaw Puzzles

I'm launching a new online jigsaw puzzle retail start-up and need a modern, minimalist e-commerce website. It’s an adult theme range, artistic drawings, not real photos. The branding needs to be dark and moody, but somehow sophisticated, representing art not p*rn!

Requirements:
- User-friendly interface for easy navigation and shopping
- Secure credit/debit card payment integration
- Modern and minimalist design aesthetic

Ideal Skills and Experience:
- Proven experience in building e-commerce websites
- Strong understanding of minimalist design principles
- Expertise in payment gateway integration, especially credit/debit cards
- Familiarity with SEO best practices to ensure high visibility
Willing to work with artistic depictions of adult content.

Please include a portfolio showcasing similar projects. Looking forward to your bids!
