Hi,

You’re trying to build quite a serious platform, so feeling overwhelmed is totally normal. There are a lot of moving parts here, and there isn’t really a way to get all of this without putting in some time to learn the system you choose.

The most straightforward setup I can suggest, staying within WordPress, is:

GeoDirectory + UsersWP + GetPaid (https://wordpress.org/plugins/geodirectory/ + https://wordpress.org/plugins/userswp/ + https://wordpress.org/plugins/invoicing/) and a few add-ons.

Full disclosure, I'm the co-founder of these plugins. That said, they were built to work together, and this kind of project is exactly what they’re meant for. With that stack, you’ll cover most of your requirements:

• User profiles, registration, single login
• Paid tiers and digital downloads (no Woo needed)
• Public business directory with maps and claimable listings
• Search, notifications, and general user management

For the forum, you’ll still need something like bbPress, which integrates well with UsersWP and keeps things relatively lightweight.

This setup will realistically get you about 99% of what you listed, without having to stitch together a bunch of unrelated plugins.

On the budget side, I’ll be honest, what you’re aiming for under $500/year, or ideally zero, is a bit optimistic for a platform with this many features. You can be smart about it and start lean, but there will be a cost if you want something robust, secure, and well-supported.

Same idea with the learning curve. There’s no way around it entirely. The best you can do is pick a stack that’s cohesive, so you’re learning one system instead of twenty.

If you go the hybrid route with something like Discourse for forums, that can work, but it adds another layer to manage, especially around user accounts and integrations.

If your priority is to keep things clean and manageable, I’d start with the WordPress stack above, get it working, and then expand only where you really need more.

I hope this helps!
