Hi Jake,
I recommend getting in touch with your local camera rental house. Check to see if they lease cameras from owner/operators. Basically, (budgets aside) you buy an Alexa package and the rental company stores it at their location. The rental company can then rent that camera out; you get like 70% of the rental and they get 30%. (Those numbers are just hypothetical. It may work out to 50-50 or even better for the rental house. It all depends on what you negotiate.) Doing this method allows you to make money back on your camera when you're not using it. You'll have to make sure a contract is drafted, of course.
As a shooter, I can't recommend the Blackmagic cameras. Personally, I've only had bad experiences with them, such as the fixed pattern noise on the BMPC 4k.
If you're going to be shooting and editing your own projects, then I recommend the FS7. It's one of the most popular budget cameras right now and packs more bang-for-buck than any Blackmagic camera. Additionally, it comes with the short focal flange distance which lets you mount virtually any lens to it (including the metabones speed booster). Check out the specs online and I'm sure you'll be sold.
One of the reasons I mentioned contacting your local rental house is because they'll give great advice on which camera to get as well, and which camera will rent more. There's a trend happening now (which I don't agree with) where producers are looking for DP's with a specific camera. The C100 is a great camera, and hell the 5D still does wonders, but the producers are looking for owner/operators with the Alexa, RED, or the hot new camera.
RED is just too post-production heavy for the low budget world and the Alexa is just too expensive for one person to own. Your only option is to own the hot new camera. Unfortunately, there's a hot new camera virtually every six months. Financially speaking, it's hard to keep up with buying a new camera system every six months.
The FS7 will last you for years, the C100 is still amazing (even though most are considering it "obsolete" now), and your AF100 is still a fantastic camera. However, producers don't think like DP's; they don't know cameras as well as you do and will research online for the "best" camera. Hence why they always ask for RED, Alexa, or the hot new one. Eventually, you'll get to the point where producers will ask you what camera to use; but until then, this is the game we have to play.
I see that you're based in Iowa? I don't know the market there, but I would wager that an FS7 would go a long way at the rental house there.
Hopefully this helps!
