AI Workflow Automation Setup

I run a small services company and would like our routine workflows to run themselves. The core stack is Google Sheets, Google Calendar, and HubSpot; I need an expert who can connect those three tools to an LLM layer—whether that ends up being ChatGPT, Claude, Grok or a mix—so that data flows automatically and triggers happen without anyone touching a keyboard. Here’s what has to happen. • Data entry & updates: whenever a quote, lead, or status change appears in HubSpot, the relevant rows in Google Sheets should populate or refresh. • Scheduling & reminders: new jobs or follow-ups added in Sheets or HubSpot must instantly create the right Google Calendar events, complete with reminder logic that can adjust if details shift. • AI reasoning: the large-language-model layer should watch these events, interpret notes or plain-language prompts, and decide which workflow to fire—saving summaries, flagging anomalies, or nudging the team when human input is required. I’ll map out the existing process and share API keys; you translate that into stable, maintainable automations. I’m happy with low-code services (Zapier, Make/Integromat, n8n) as long as the solution is transparent and can be handed off cleanly. Acceptance criteria 1. All three platforms stay in sync in real time. 2. No duplicate or dropped records during a two-week live test. 3. Clear hand-off documentation covering triggers, endpoints, and how to swap one LLM provider for another. If this sounds straightforward to you, let’s talk about timelines and get it launched.
