Welcome.
I would recommend the CH Products Fighterstick and Pro-Throttle, if you can't afford the Warthog setup. The throttle doesn't match the Hawg (and is not split), but it works really well, and is really flexible. From your photos, it looks like you already have the matching Pro Pedals. I've been using their products for at least 10 years. The Fighterstick is the exact layout of the Hawg stick except you don't have a two-stage trigger, or the Z-axis on the CMS Button. You can get around that by using the CH Control Manager Software. Amazon has them both for around $97 US each.
I've had the CH Products since before I met my wife. I would not survive to even play a sim if she found out I bought the Warthog setup, so I'm happy with my existing controllers.
