Python dialogflow google chat chatbot questions and code samples - Quotation Request

Please provide your estimated total development price in AUD 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 have a dialogflow google chat chatbot that runs in GCP App Engine running Python for the Fulfilment. I am looking for someone experienced in this environment and technology as I have some questions I need solved. The chat bot works and is live to a large customer base but I need to add some new functionality which requires the use of sessions and context. Initially I would like someone with experience to answer some questions around the sessions and contexts and provide some sample code / screenshots. If it works then I may continue the engagement whilst implementing the ideas. For now just the initial engagement as described. Estimating assumptions and context: The scenario is based on a Freelancer listing from 2023-03-05 (historical project ID 36127200). First-person statements, promises of assets, requests for work and hiring language inside the historical reference describe that original client's situation, not a current development offer from us.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 AUD 10–30 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.
