Vibrant Tkinter GUI for Library Management System - 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'm looking for a Python Tkinter expert to create a simple yet colorful and vibrant GUI for my library management system. The core functionality of the system includes handling the borrowing and returning of books, as well as searching and cataloging them.

Key Requirements:
- Design a GUI that is colorful and vibrant, yet intuitive and easy to use.
- Implement user roles: Admin and User.
- Ensure the GUI supports the core functions of the system.

Ideal Skills and Experience:
- Proficiency in Python with extensive Tkinter experience.
- Previous work designing colorful, vibrant GUIs.
- Understanding of library management systems is a plus.

Estimating assumptions and context:
The scenario is based on a Freelancer listing from 2024-11-18 (historical project ID 38801261). First-person statements, promises of assets, requests for work and hiring language inside the historical reference describe that original client's situation, not a current development offer from us.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.
