Afghan Cash Website Development

I need a secure website called Afghan Cash to help Afghans earn income. The platform's main feature is yet to be decided, but could be a freelance job marketplace, an online store, or a content creation platform.

Key requirements:
- User verification via email
- Security features like data encryption, two-factor authentication, and regular security audits
- Protection of all rights, privacy, and the integrity of my idea

Ideal Skills and Experience:
- Experience in developing secure, user-friendly websites
- Strong background in implementing robust security features
- Familiarity with user verification processes

Please provide a reasonable development cost.
