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:
A mobile app (android and iOS) that enables people to barter trade used items. The mobile apps can be done even using cross platforms like React or flutter and can even be implemented on platforms like firebase. Will require a web admin panel to manage the app data.
Key features:
1. Upload Item/Service eg
Item: Trade your pair of jeans for a pair of jacket. Snap a photo and give it a description.
Service: Good at graphic design? Develop a logo for someone for a pair of computer accessories.
2. Search/Filter: You can filter by distance, value range, or categories to get exactly what you want. You can also filter by what others want, so if you have it, you can make the trade happen.
3. Propose a Trade: The platform to allow the user to trade any combination of items. Eg 3 items for 2, or 1 service for 5 items…just about any combination. The two people can chat, negotiate and agree before trade is sealed.
4. Carbon points (reward points):
System assigns carbon points based on the item uploaded (based on preloaded data), which can be tracked in the user’s profile
5. Delivery of the items: Once the user accepts a ‘received’ trade, or a trade they ‘sent’ is accepted by someone else, that’s a trade made!
The 2 persons can decide to:
• Chat and Meet-Up and exchange
6. Rate : the user can rate the person whom they have traded with, and leave feedback.
Estimating assumptions and context:
The scenario is based on a Freelancer listing from 2022-01-17 (historical project ID 32664565). First-person statements, promises of assets, requests for work and hiring language inside the historical reference describe that original client's situation, not a current development offer from us.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.
