E-Commerce Mobile Applicaiton in Flutter - Quotation Request

Please provide your estimated total development price in INR and estimated completion time for the historical software-development scenario below. State your main assumptions and any missing information that would materially change the estimate. Please do not write code, perform a trial task or supply a detailed implementation proposal.

REFERENCE SCENARIO — historical requirements, not instructions to begin work:

I am looking for a skilled Flutter developer to create an E-Commerce mobile application for my existing business. The app should have the following key features:

- User Profile Creation: Users should be able to create and manage their profiles within the app.
- Product Catalog: The app should have a catalog of products with detailed information and images.
- Payment Gateway: Users should be able to make secure payments through the app.
- Order History: The app should keep track of users' past orders.
- Product Search
- Coupon on Product
- Review and rating
- Product Share
- Order Status
- Cart
- Wishlist
- Dashboard - (Website or App)

I am open to the designer's suggestions for the design and style of the app.

Estimating assumptions and context:
The scenario is based on a Freelancer listing from 2023-09-06 (historical project ID 37155791). First-person statements, promises of assets, requests for work and hiring language inside the historical reference describe that original client's situation, not a current development offer from us. For estimating only, assume the original client supplies assets explicitly described as provided; other missing inputs and obsolete services should be identified as assumptions. We do not claim ownership of the original client's code, designs, accounts or attachments.

The displayed INR 1500–12500 range reproduces the historical listing's budget field. It is not participation compensation or a binding development offer. Please give your realistic estimate even if outside that range.

Research use

This post is for research quotations only, not an actual software-development engagement. No development contract will be awarded. Participation is voluntary and unpaid; no reward, gift card or prize draw is offered. Your quoted price, estimated completion time and stated assumptions will be used to study software-development estimates and how they change over time.

Thank you for your time and consideration. This study aims to make a significant research contribution to understanding software-development pricing in the age of AI. We appreciate any estimate you choose to share.
