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 have a problem setting up woocommerce Subscription with a time setting: If a customer buys more than 1 product, then the membership period (month) will accumulate it. Not only that, it also accumulates the remaining previous membership automatically. In general, this must be flexible, for example, someone buys product A on the 1st of January and product B on the 5th of January, then if they buy 2 products A and 1 product B on the 25th of January, I want the payment display and membership history of product A to be extended until the 1st of January and product B until the 5th of January.

I created a code to assign roles specifically based on product ID and wcpa that can be assigned specifically, but it is not certain that it can be deleted specifically if the above problem has not been resolved.

I want to work with a developer who can really complete the project, not just try to take it and who is also ready to be asked about the progress. Because I am also a developer, so I hope there is someone who is much more professional and can finish as soon as possible. For the budget, give a reasonable budget.

Estimating assumptions and context:
The scenario is based on a Freelancer listing from 2024-09-13 (historical project ID 38568420). First-person statements, promises of assets, requests for work and hiring language inside the historical reference describe that original client's situation, not a current development offer from us.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.
