Automated Software P2P Marketplace Development

I'm seeking a freelancer to create a fully automated website for peer-to-peer transactions involving the buying and selling of software. The platform should function similar to a marketplace and affiliate program, where transactions conducted through referrals can be easily tracked and approved by the main user before payment is released to the referrals.

Key Features:
- Comprehensive legal compliance
- Integrated payment setup
- User reviews and ratings
- Escrow service
- Automated dispute resolution
- During the purchasing process, users pay the invoice and upon successful payment, goods are delivered
- For sales, the user sends a request to a secondary user who has provided a referral

Payment Methods:
- Credit/Debit Card
- PayPal
- Cryptocurrency
I am aiming to cater to overseas clients, therefore I'm looking for a solution that employs the lowest fee gateway available.

In addition, I intend to purchase some pre-made graphics, themes, modules, etc. for resale on my website.

Ideal candidates will have:
- Proven experience in developing similar e-commerce platforms
- In-depth understanding of P2P transaction systems
- Knowledge of legal compliance for digital marketplaces
- Ability to recommend cost-effective payment gateways
- Skills in sourcing and integrating pre-made website content
