Enhance Jobify Functionality

My Jobify-based WordPress site needs to move beyond its out-of-the-box setup. I’m looking to roll out three key features and would like a developer who already knows the Jobify structure, WooCommerce hooks, and front-end tweaks in HTML/CSS.

Here’s what I need done:
• Advanced search filters that let visitors drill down by category, location, salary range, and any custom taxonomy Jobify exposes.
• A smooth user registration & login flow (social logins welcome) that blends perfectly with Jobify’s profile system.
• Payment-gateway integration so employers can pay for premium listings or upgrades during checkout.

I don’t have fixed plugins in mind, so please recommend the most reliable, well-supported options—or propose custom code when that makes more sense. Whatever we use must stay lightweight, compatible with future Jobify updates, and easy for me to maintain.

Deliverables are:
1. Fully implemented features, styled to match my current theme.
2. Admin-side toggle or settings page so I can manage each new function without touching code.
3. Brief documentation and a short walkthrough video or call showing me where everything lives.

If you’ve previously built advanced search modules, custom login flows, or stripe/paypal add-ons inside Jobify or a similar job board theme, let’s talk.
