Looking at your pictures, I don't know how you can breathe riding a bike set up like that. Your abdomen is all scrunched up. Your diaphragm probably can't move up and down a fraction of its range.

You don't need a $200 fit. All the information you need is easily available on the internet. Start with the basics and just fit yourself according to the usual rules of thumb - no matter how often these get "debunked" on various websites and internet forums. That's all it takes to ride with reasonable comfort and efficiency, and without injury. Then, you can fine tune it by experimenting a bit with saddle height and setback, or in response to any pain you might get after riding (such as in your back or knees). Later, get a pro fitting when you can afford it, but personally, unless you're a pro cyclist who needs to compete with all the other pro cyclists and you need to squeeze out every drop of performance, I just don't see the need for that.
