Go-Kart Race Management & Live Display System - Quotation Request

Please provide your estimated total development price in USD 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 in need of an experienced web developer with PHP and MySQL expertise, for a comprehensive go-kart race management website. This site will also be integrated with a mobile app for scanning drivers in and out.

Key Features of the Website:
- Driver registration and profiles
- Race scheduling and tracking
- Race results and statistics
- Building of Championships, rounds in championships, teams, drivers, etc.

In addition, the website will serve a very specific purpose of displaying live race results on TV screens. Therefore, experience in creating dynamic content is essential.

The ideal freelancer for this project should have:
- Proven experience in PHP and MySQL
- Prior work with e-commerce or community/ forum websites
- Skills in mobile app integration
- Ability to create dynamic content

Please include examples of similar projects you've worked on in your proposal.

Developers who live in Thailand and speak English preferred.

Estimating assumptions and context:
The scenario is based on a Freelancer listing from 2024-11-18 (historical project ID 38801700). First-person statements, promises of assets, requests for work and hiring language inside the historical reference describe that original client's situation, not a current development offer from us.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 USD 250–750 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.
