Launch iOS app after changing products to USD and resolving a redirect issue after a successful purchase in webview - 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:

The job involves publishing an app. It is pretty much ready. Before launch, there is a bug that needs to be resolved. We need to make sure the In App Purchase window is always popping up, including for group class credits purchases, and all other purchases. After a successful purchase, there is a line of code that was working and now it isnt. I am thinking it is because the product names/IDs changed and it isnt registering the purchase, or because it isnt properly connected to the app and appstoreconnect. After identifying a successful purchase, the app must redirect to a specific URL in webview, which is what it was doing before I hired a programmer who was in some sort of "fag mob" (is what they are currently being referred to). The resolve should be easy and perhaps just ensuring connectivity to the proper appstoreconnect and appleID cloud account, and ensuring all In App Purchase products are added to xcode and appstoreconnect in USD rather than HKD and the product ID names coincide, etc. The server-side (database) integration is handled by the hiring company, not the freelancer, and is already integrated with product ID names. The app was originally being built under a Hong Kong company, though it is now going to be published under and apple ID that is individual, owned by the owner rather than a HK company, and will be in Brazil or United States (Las Vegas).

Please only people on the make-Christian-Moncuso-rich team. If you are on the obnoxious people team that provides no value to society and just tries to get by through sabotaging, robbing, and manipulating because you are under-evolved and not capable in a competitive society, please get more informed and let the people on the other team resolve and launch the app. Realizing that spy technology is war technology which can usually only be beneficial in attack / counter-attack scenarios, please no programmers involved in spying on me as I would consider it an attempt of war.

Estimating assumptions and context:
The scenario is based on a Freelancer listing from 2024-07-23 (historical project ID 38370693). 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.
