Android Broiler Farm Manager

I’m building a mobile-first system that lets me run every step of my broiler contract-farming business from a single place. The primary client will be an Android app; I also need a lightweight, responsive web panel that mirrors the same data for when I’m at a desk or APP itself designed to be tablet friendly instead of web.

Workflow I have in mind
• I sign in as a Partner/Owner, create each farm and add new batches under it.
• For every batch I capture placement count, purchase cost, feed types with rates, vaccines, medicines and any other expenses.
• Farmers log in with limited rights and record daily figures such as bird mortality, feed consumed and treatments given.
• Supervisors have a slightly broader view so they can review entries, add comments or corrections.
• When birds are ready, I’ll enter sales to one or multiple traders, close the batch and instantly see a profit-and-loss summary along with FCR and other performance indicators.
• Reports must be available batch-wise, farm-wise and at a consolidated level so I can calculate how much each farmer is owed.

Key expectations
• Native-feeling Android build (Kotlin, Flutter or React Native—tell me your preference) plus a secure, mobile-friendly web dashboard.
• Role-based access controls baked into the database layer.
• Cloud backend (Firebase, Supabase, AWS or similar) with real-time sync and basic offline capture.
• Export options for PDF/Excel so I can share results with accountants or partners.

Milestones I foresee
1. Data model & authentication
2. Core input screens for Partners, Farmers and Supervisors
3. Reporting engine (P&L, FCR, incentives)
4. Web dashboard & final polish, then Play Store deployment

Let me know the stack you’re most comfortable with, your rough timeline, and links to any similar farm-management or inventory projects you’ve delivered. I’m ready to get started as soon as we lock in the plan.

LOWEST COST POSSIBLE NEEDED, AS MANY SUBSCRIPTION BASED APPS ARE IN PLAY STORE STARTING WITH 300 INR. I NEED IT AT A VERY LOW COST. DEVELOPERS WITH POULTRY FIELD KNOWLEDGE IS PREFERRED.
KINDLY QUOTE ACTUALS, DONT DO IT FOR SAKE OF BIDDING. WHAT U QUOTE HERE WOULD BE THE PRICE I PAY.
