Rental Boyfriend Platform Development

I am building an online platform that matches people who want to rent a boyfriend for a set period with individuals offering that service. Two clear user groups will drive the product: renters (clients) and rentees (the boyfriends).

For the renter side, I need three core experiences implemented end-to-end:
• They must be able to browse detailed profiles, complete with photos, bios, and public reviews.
• From any profile, they should start a private chat to ask questions or discuss expectations.
• Once ready, they can secure a time slot by booking an appointment in an intuitive calendar flow that confirms instantly.

Rentees will require a parallel dashboard where they edit profiles, respond to messages, manage availability, and see upcoming bookings in real time. An admin layer will sit behind both sides to monitor activity, verify identities, and step in for support where needed.

I am open to the tech stack you are most comfortable with as long as the finished product is responsive on mobile and desktop, supports secure authentication, and can be extended later to integrate a payment gateway. When you reply, please outline your preferred architecture, any similar platforms you have built, and how long you expect each milestone—profile module, messaging, and booking—to take.
