WooCommerce / Elementor Developer Needed – Fix Mollie Phone Number Validation (Small Task)

I'm looking for an experienced WooCommerce + Elementor developer to fix a checkout issue on my website (deusphos.com). The issue We use Mollie as one of our payment providers. Currently, if a customer enters their phone number without an international country code (e.g. +30), Mollie rejects the payment after clicking "Place Order" with an invalid phone number error. As a result, the payment cannot be completed. What needs to be done 1. Identify how the checkout phone field has been implemented (Elementor/custom form/plugin). 2. Make the phone field mandatory. 3. Implement a solution so customers must select or enter a valid international country code (preferably using code, but a lightweight, reliable plugin is also acceptable). The solution should be user-friendly and work well on both desktop and mobile. 4. Test everything on a staging/test environment to ensure Mollie accepts the phone number and payments complete successfully. Requirements Strong experience with WooCommerce Experience with Elementor checkout Experience with Mollie Payments Clean coding practices (prefer custom code over installing unnecessary plugins) Budget / Scope This is a small, clearly defined task. An experienced developer should be able to identify the issue and implement a solution relatively quickly (around 1–2 hours, assuming no unexpected conflicts). Please only apply if you have experience with similar WooCommerce checkout issues.
