Community Networking website using wordpress

**please send a sealed quote

I need a Community / Networking platform developed using wordpress.

Apart from the basic networking functionalities, it should have
- registration with OTP verification
- chat feature with admin moderation and monitoring
- ability to have customized free and paid plans
- ability to report post/profile
- ability to sell advertising space
- separate privileges for service provider and service seeker

Please discuss the options for community scripts/themes and plugins you would use in your prroposal.
Also, mention the community websites you have built.
You can also mention reference websites that I can see to understand what all features you would provide.

All the best.
