Online Casino Website Development Needed

I’m looking for a full-service partner to build a real-money online casino focused mainly on slot machines. I need the complete website—front end, back end, and game content—delivered production-ready.

Game content
• Slot machines are mandatory.
• I’m open to either integrating trusted third-party slots or having comparable originals developed from scratch; suggest the most efficient route and justify it.

Core platform requirements
• Player registration, KYC, and account management
• Secure wallet with multi-currency deposits and withdrawals
• Provably fair RNG or relevant certification for all games
• Admin dashboard for user, game, and finance oversight
• Scalable architecture that handles high traffic without latency

Site features
• Mobile-first responsive design
• Bonus/loyalty system configurable by the admin
• Geo-IP tools for region control and compliance
• Basic localization framework so I can add languages later

Please outline:
1. Your preferred tech stack and any iGaming engines or APIs you’d use.
2. Licensing or compliance guidance you can provide (if any).
3. Estimated timeline broken into milestones—from initial wireframes to final launch.
4. Required third-party costs I should budget for (game licenses, hosting, security audits, etc.).

I’m ready to move quickly once I see a clear, realistic plan and previous casino or betting projects in your portfolio.
