Hey Sean I feel your pain man. I usually use Audiojungle quite a bit, after a while their music starts to sound repetative though. they also have various different pricing models. Premiumbeat is cool but too expensive again with many different pricing models.
Another cool one I found was 909 Music. Good quality stuff and cheaper than the others. they also have something called the marketplace where you can post a request of sorts and even mention your budget and suprisingly enough you get music sent to you by composers. I am using them a lot these days and I highly recommend their service, it’s one of the best in in my opinion. You can find them at https://www.909music.com and the marketplace is at https://www.909music.com/marketplace
Then you have really cheap and free ones like Incompetech, Bensounds and Danosongs. Give everyone a shot and see what you like!
Hope this was helpful enough
