n8n PDF OCR GoHighLevel automation

I need an experienced n8n automation developer to build a workflow that processes mortgage protection lead PDFs. The system should automatically take a multi-page PDF (often containing hundreds or thousands of lead forms), split it into individual pages, extract the lead's name using OCR or template-based data extraction, rename each image file using the client's name, convert each page to JPG or PNG format, and save the files to a designated folder. The workflow should also handle duplicate names, OCR errors, and provide a simple review process for exceptions. As a second phase, I want the automation to integrate with GoHighLevel by locating the matching contact record and attaching the lead image to that contact automatically. Experience with n8n, OCR, PDF processing, Python, APIs, and GoHighLevel is required. Please provide examples of similar automations you've built and an estimate of timeline and cost.
