There's always ways. Depends how you want to try it really,
You could find unestablished artists/beatmakers on soundcloud/soundclick/forums who either offer tracks for download to use, or are willing to give free beats which is a good shout.
Or more established ones that might give you a beat to use, from tracks they've done it does happen.
If not straight up asking for beats, offer to collaborate with the artist, even if they openly say they are or not, it's always worth a try, especially if you enjoy their work.
I'd definitely try this, there are always people creating and wanting someone to work with, and take their work and build on it, so don't stop trying this until other options open up, you don't know where things could lead anyway, fostering good relationships especially locally in your scene and elsewhere is very helpful and can transcened just business and music as a whole.
If you wanted to find royalty free beats and the like to download there's a lot of sites of course to download from, but then you wouldn't be the only one with the beat so that's kind of an obvious trade off.
Or just searching like 'free hip hop beats', and there's people with free mp3's etc for use sometimes for non-commercial use though.
Found this randomly: for example SoundClick artist:

Seen this now for a while, it's a video site where producers can upload beats, then other users/rappers/vocalists, record a video with their lyrics on that beat, added a link to a producer I follow as well, the site might interest you a little:

When it comes to producing your own beats you don't 'need' to know music theory and what chords are for what etc. If that gives your mind that feeling of safety via 'understanding' that's fair, you can learn theory of anything in life, but you're still skirting around the pool watching everyone else swim, when the only real way to learn is by jumping in and figuring it out through your own experience, creating good habits along the way so even when you aren't feeling inspired you'll stick at creating and doing what makes you happy in the long run.
It always takes practice and time like anything, and there are always multiple ways to approach things, cause you have to figure out what works best for you when creating, and trying different things out helps you figure that out. Ableton is awesome though, I and a lot of people I know use it, although I mainly use mostly samples or sometimes a keyboard if I'm messing around with ambient kinda stuff.
One friend I know mainly uses a lot of sounds from Ableton, or plugins/synths etc, so it's definitely just a process of becoming aware of how you like to do things, if it's like just on an MPC or all on a laptop or whatever, limitations in a way are valuable even if you feel they are holding you back from creativity, it pushes you to be more creative, and this a lot of the time is how people learn to find their own style by just using certain things and getting something different out of them, or using them to create something original to them. You can do a lot with a little.
You can make a lot of awesome art with the worst equipment, crappy pc's, broken mpc's etc, you don't need good brushes to paint a masterpiece, the vocals of one of my favourite uk hip-hop/rap albums out recently was recorded via usb soundcard, on an old mic with a sock for a pop filter. Obviously you might have some standards for what beats you want to rap on, and the style of the beats or who the producer is etc. However sometimes all you need is to take that step, and put yourself out there even no matter what and your intention to go on that journey to manifest the kind of future you want, that action will attract others, some people might not like it but what you think is the only important thing, believing in yourself, and taking action creating something is all that matters, and people will follow.
