Crypto Freelance Platform Development like botdigit .com

I want to build a full-featured, crypto-based freelancing marketplace modelled on botdigit.com. The core flow should let clients post jobs, freelancers bid, and both parties complete payment entirely in crypto, all under one roof.

Key capabilities I expect from day one:
• Secure user accounts with public portfolios, ratings and a clean dashboard for both freelancers and clients.
• A smooth job posting and bidding system that supports milestones, dispute handling and real-time notifications.
• An integrated payment gateway with internal wallets that handle Bitcoin, Ethereum and Ripple deposits, escrow, release and withdrawals without relying on third-party exchanges or KYC providers for now.

Tech stack is your call—Laravel, Node, React, Next, or a comparable modern stack—as long as security, speed and maintainability guide every decision and the code is well-documented.

Deliverables
1. Complete front-end and back-end source code in a private repo
2. Database schema and migration scripts
3. Admin panel with user, job and finance controls
4. Installation guide and deployment support to my VPS
5. A short walkthrough video showing account creation, job flow and a test payment in BTC, ETH and XRP

Acceptance criteria: all three coins must go from deposit to escrow to release flawlessly on testnet, and the UI must respond under 2 s for common actions.

If you have built similar marketplaces or crypto wallets before, let me see a live link or a short code sample so I can gauge fit quickly.
