We are looking for an experienced WordPress / WooCommerce developer to build a custom quote request configurator system on our product pages. This is not a standard e-commerce checkout project. We do not want a classic add-to-cart and purchase flow. Instead, we need a structured model-based quote request system for industrial machines, with configuration options and automatic quote document generation. Our website is built with WordPress and WooCommerce. Each product page represents a machine series, and inside each product page we already show a table that lists all available models of that machine. For each row in that table there must be a “Request Quote” button that is linked to that specific model. This system must be designed so it can be reused on all products later, but for now we only want the developer to fully implement it on one product as a working example and then explain the setup, because we will replicate the same structure ourselves on the other products since we know internally all model options and pricing rules. When a visitor clicks the “Request Quote” button for a specific model row, a popup or modal window should open without forcing a page reload if possible. Inside this popup, the model related to the clicked row must already be prefilled automatically. The popup must allow the customer to select optional accessories and extra features using multiple checkboxes, since more than one optional item can be selected. The popup must also include customer contact fields such as name, email, phone, and message. When the form is submitted, we must receive a structured email containing the product name, selected model, selected optional features, and all customer contact data. A key requirement is that product prices and optional prices must be configurable in the backend by us for every product and every optional feature, but they must remain completely hidden on the frontend. Customers must not see any prices, totals, or cost calculations anywhere on the site. Prices are only for internal use. Based on the selected model and optional features, the system must automatically calculate the total internally and generate a PDF quote document. This PDF must be automatically attached to the email we receive, already formatted as a ready-to-send quotation including customer data, selected model, selected options, and calculated prices. The goal is that when a request arrives, we already have a finished quote PDF ready to forward to the customer without manual preparation. Even if WooCommerce is used as the technical base, the user experience must behave like a configurator and quote request interface, not like a traditional online store. We do not want the standard cart and checkout flow visible to customers. The model table is already present inside the product content using a table plugin, so each row button should pass the model value dynamically to the popup form. Optional features must be configurable per product, since each machine has different accessories and different pricing. The implementation should be clean, maintainable, and reusable across multiple product pages. The final user experience should be fast, simple, and mobile-friendly: the customer selects a model from the table, opens the popup, chooses optional features, submits the request, and we receive both the email and a ready-made PDF quote with all configuration and pricing included internally. In your proposal, please explain what technical approach and plugins you would use to implement this and confirm that you can deliver it first on a single product and document the setup so we can reuse it on the others.
