Rebuild existing Base44 Calculator in WordPress + Elementor (Free Version)

I am looking for an experienced WordPress developer to recreate a Budget Calculator & Expense Tracker that I have already designed in Base44, and implement it natively in WordPress.

Live reference (Base44 calculator):
https://up-task-pro-build-budget-pro-dc6246b9.base44.app

The goal is to faithfully recreate both the layout and the calculation logic inside WordPress while keeping the solution:

Update-safe

Lightweight

Compatible with Elementor (Free version)

Fully compatible with the Workreap theme

Mobile Friendly

This is not a generic calculator — it reflects real-world construction budgeting logic and must behave accurately.

Scope of Work
1. UI / Layout Recreation

Recreate the visual layout of the Base44 calculator in WordPress

Match spacing, section hierarchy, and usability as closely as possible

Use Elementor Free where feasible

Custom HTML/CSS/JS is acceptable where Elementor is insufficient

Styling must integrate cleanly with the Workreap theme

2. Calculator Logic & Functionality

Line-item budget inputs

Category subtotals

Grand total calculation

Contingency calculations

Automatic updates when values change

Clean number formatting (currency, percentages)

The calculations must match the Base44 version exactly in behavior and output.

Technical Requirements

WordPress (latest stable)

Elementor Free (no Pro features)

Workreap theme

No core theme file edits (child-theme safe)

Clean, readable, well-structured code

JavaScript-based calculations preferred (no page reloads)

What I’m Looking For

✅ Strong WordPress fundamentals
✅ Elementor (Free) experience
✅ Comfortable with custom JS for calculations
✅ Experience working around theme limitations
✅ Attention to detail (layout + math accuracy)
✅ Ability to follow an existing reference precisely

Deliverables

Fully working calculator embedded in a WordPress page

Matches Base44 layout and behavior

Clear explanation of:

Where code lives

How calculations work

How to edit or extend later

Nice to Have (Not Required)

Experience with financial calculators

UX/UI sensibility

Performance optimization awareness

This project is part of a larger platform build, so future work is possible for the right developer.

I value clean execution, accuracy, and communication over speed.
