We are looking for a WordPress developer who will create an interactive cost calculator for a modular house — as a widget or shortcode that can be embedded on a website. The calculator should work on a single screen, instantly update the cost (via AJAX), and allow the client to play with parameters (type of house, area, number of bedrooms, options, utilities, etc.).
What needs to be done:
- Implement the calculator as a WordPress plugin or widget.
- On the frontend: a single-page configurator that shows an estimated price in real-time.
- On the backend: a user-friendly admin panel for editing basic models, options, and costs.
- The cost calculation should take into account:
the basic model (type of house, 1–2 floors, area);
additional options (kitchen, furniture, utilities, design project, Smart House, etc.); interdependencies of parameters (for example, 2 floors ≠ ×2 in price, area affects the base price and furniture).
- The total should be displayed immediately without reloading.
