Redo Website and backend - site built using Claude

​We have a live web application that pulls job postings via an API, uses an AI model to rewrite the descriptions, and displays them to users. Our previous developer built the frontend via AI, but is withholding the source code and refusing to cooperate (oddly a longtime friend who did this for free and refuses payment - he wants to focus on other personal projects and come back to this in 3 months - we can't wait on that). We need a full-stack developer to build a clean, SEO-optimized frontend from scratch on our own hosting (you can use the current existing site layout which just went live), reconnect our job board API and AI rewriting logic, and implement proper JobPosting JSON-LD schema so Google indexes our jobs correctly. The url is Merkergroup.com. I can share backend via screenshare, so you can see the semiautomatic job posting process. It also pulls in attorneys from a 3rd party product that help identify the right attorneys for us to reach out to for a role (we are legal recruiters). The site also is up (but we have no interface to make changes). We need the ability to easily view the attorneys and ultimately build automation so that when a new job comes in via API, we can automatically send a custom AI generated email message selling the correct attorneys on the job. I can explain further on a call. Preference is for project based pricing - but keeping this open ended for now.
