Custom AI Website Builder WordPress Plugin (Text, URL & Screenshot to Website)

We are a SaaS hosting company looking for a highly skilled WordPress/PHP developer with AI integration experience to build a custom, white-labeled AI Website Builder Plugin.

Core Functionality:
The plugin will allow our end-users to generate a complete landing page/website inside their WordPress dashboard with a single click. The user should have the freedom to use one or a combination of the following inputs:

Text Prompt: A description of their business.

Screenshot (Vision): Upload an image of a website design they like.

Target URL: Paste a link to a reference website.

Key Requirements:

LLM Agnostic: The plugin MUST NOT be hardcoded to OpenAI. The admin settings should allow us to plug in any API key (e.g., Anthropic Claude, Google Gemini, OpenAI, or OpenRouter for open-source models).

Page Generation: The AI should analyze the inputs (vision/scraping/text) and inject the generated structure, content, and placeholder images into a native WordPress page (compatible with Gutenberg or Elementor).

100% White-Label: The frontend UI for the user must be clean, modern, and completely brandable (No third-party logos or credit limits shown to the user).

Credits/Limits: A simple admin setting to limit how many times a user can generate a site per month.

Ideal Candidate:
You must have proven experience building custom WordPress plugins and working with REST APIs, particularly LLM APIs (Text & Vision). Please share examples of similar AI/WordPress projects you have completed.
