Deploy booking app - Quotation Request

Please provide your estimated total development price in CAD 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:

Hi I am looking for a dev who has already done an app with the following. The idea is to re-brand and adapt what has already been done. We can also buy a template. We need to have this app in a delay of 2 weeks.

The projet is to deploy a booking app for small service compagnies. The idea is to help them reduce staff or fees by automating reservation.

-Add multi organization and SAAS feature to template or the app you have done.
-creat a dashboard with all the services by category and geographic. (End user can filter and search for the hair dresser in his city and book)

Merchant features
-Landing page and CMS for each merchant
-Merchant makes availability in backend
-Can connect with google or Outlook calendars
-Merchant gets notification by email and calendar when booking happens.

End user features
-user selects a service provider according to filters (geolocation ect)
-user selects a time frame.
-user selects the service
-user enter: name, cell phone
-user gets an sms confirmation
-24 hours before the appointment users gets sms to confirme. The merchants can make confirmation from end user mandatory.
-If confirmation is mandatory and no confirmation the time frame becomes available.
-The non confirmation are sent to a waiting list of users who want to be notified. (First confirmation wins)
-If user selects a non confirmation time frame his initial time frame becomes available.
-after appointment end user gets a rating of his experience by sms. A simple 1-5 star ratting and comment can be left.

Estimating assumptions and context:
The scenario is based on a Freelancer listing from 2022-08-27 (historical project ID 34480000). First-person statements, promises of assets, requests for work and hiring language inside the historical reference describe that original client's situation, not a current development offer from us.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 CAD 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.
