Experienced Mobile App Developer Needed

What We Need Before starting development, we'd like an experienced mobile developer to review our requirements and provide: A realistic MVP assessment Technical recommendations Development roadmap Estimated development hours Estimated project cost Suggestions for simplifying the MVP if needed Recommendations for future scalability We're looking for someone who can think like a technical partner, not just provide an estimate.

If you reviewed an MVP and felt it was too large, would you recommend simplifying it? Are you comfortable signing an NDA before reviewing the documentation?
