N8n Automation Development required

I need an n8n developer to deliver a suite of automated workflows, with a focus on integrating Gmail, Google Sheets, LinkedIn, and OpenAI GPT. The goal is to streamline daily research, outreach, and document generation tasks. The full specification document is available, along with a working JSON template for Part 1 (Email Answering & Drafts) which just requires credential tweaking.

Workflows to Build:

1. Email Answering & Drafts

Categorise Gmail inbox and draft replies using GPT based on a training folder (or external file).
Replies saved as drafts, not sent.
JSON template provided – only needs API and folder tweaks.

2. Company Contact Research

Input: Company name + keyword from a Sheet.
Perform Google search, extract key insights with GPT, find LinkedIn profile if available.
Append all data to original Sheet.

3. LinkedIn Invite Sending

Uses a Sheet with profile URLs and names.
Sends connection requests with a custom message.
Marks "Connection request sent" in Sheet.

4. LinkedIn Group Post

Posts prewritten content into groups listed in a Sheet.
Updates post status back in the Sheet.

5. LinkedIn InMail Sending

Sends personalised InMail to profiles listed in a Sheet.
Updates Sheet with "InMail sent" status.

6. Business Note Creation

Uses a Sheet + a custom GPT prompt to generate business notes.
Outputs to Word file and sends automatically.

7. Append Company & Email URL

Searches Google for company URL and email domain (e.g., “@company.com”).
Appends both to original Sheet row.

All workflows must be delivered in working n8n format with screen recording walkthroughs of the setup, editable variables etc. Full document + JSON template for Part 1 available.
