A small Python code for invoice parsing

I have a small python script deployed via GCP, it uses Invoice2data library to extract invoice PDFs and output structured JSON. Regex is what's being utilized heavily to define each invoice template (we have about 20 predefined templates.) I need to add a few new suppliers and do small tweaks so that the output is perfect, are you available to help. Requirement: 1. Experience with deploying Python using GCP cloud Run/Cloud build; 2. Expert level Regex writing skill is a MUST; Scope of the project: First of all, the project will take 2 months to complete ONLy because we can only test a few invoices each day; We will only call on your help if there is an issue. The maximum bug report will be 10 instances (Same bugs don't count if occurring...), the maximum of new supplier template to be set up will be 5. Requirements: 1. Demonstrated GCP cloud build/run experience; 2. Demonstrated Regex writing skill;
