Interactive Web App Front-End Developer - Quotation Request

Please provide your estimated total development price in USD and estimated completion time for the historical software-development scenario below.

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

My project requires a talented and knowledgeable Front-End Developer, specifically adept with React.

I am looking for a freelancer to modify and add front-ends to a full stack project, but he only has to modify the code until it becomes responsive and using dummy data, and the project should be ready with much of it within two days if possible due to the urgency.

The following must be modified and added:
- The bookmark button must be on
- Interaction with comment, post and stories such as Facebook LIKE, DISLIKE, LOVE, EMPHASIZE, QUESTION, HAHAHAHA
- Follow button is on
- Group chat If it is possible to put dummy data for a group in messages
- Can create group chat to create a group and search for friends
- Can reply to story to any story from my friends
- In my story as a User I can see the story replies and viewers by adding setting icons and it show the replies, viewers, delete story as a small component above the story and it specific for each story
- Can share post and when click in sharing it show him a confirm button and share the post in profile
- When click in “MY STORY” it show to see story if it exists or create story if it click to create story it show a small component similar to create post but here just add the file without anything else, it can be in small component and all the background is grey

Estimating assumptions and context:
The scenario is based on a Freelancer listing from 2024-05-25 (historical project ID 38148687). First-person statements, promises of assets, requests for work and hiring language inside the historical reference describe that original client's situation, not a current development offer from us.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 30–250 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.
