MVP Development – Language Learning Marketplace

Hello,
I am planning to build a language learning marketplace platform similar to Preply and would like to understand the realistic development cost and timeline for an MVP version.
The goal is not to replicate full Preply, but to launch a lean version first.
⸻
Core Concept
The platform would include:

• Student and tutor registration

• Role switching (one account can act as both student and tutor)

• Tutor profile pages

• Lesson booking system with calendar

• Stripe payment integration

• Platform commission logic

• Basic admin dashboard

• Multilingual-ready structure (English and Japanese)
⸻
At this stage, I would like to understand:
1. Estimated cost range for an MVP
2. Suggested scope reduction for Phase 1
3. Recommended tech stack
4. Estimated development timeline
Please share similar projects you have worked on.
I am looking for a long-term collaboration after MVP launch.
Thank you.
Contract duration of 1 to 3 months. with 30 hours per week.
Mandatory skills: Web Development, Google Analytics
