Need help with a build

Hey Guys, first time poster here. I have recently started in the drone market. I have bought a few $100-$200 drones and taught myself how to fly and repair the drones. But I want something more. I want to build my own drone with a nice camera that I can view live. The frame I want is linked here:

Frame: Readytosky S500 quadcopter frame
I found a motor and esc combo that I think will work good here: LHI 4x 2212 920KV Brushless Motor

Now is the part where I am a little confused. I have no idea which propellers would be good for those motors, and I also don't know about Power distribution boards, flight controllers, or how to do live feeds. I really want a camera that sits under the drone, like a cheap go pro. But I do not know what that would work with. So I basically need some recommendations for the rest of the gear. Not trying to spend a whole bunch of money, I'm trying to keep the whole thing under $300.

Any and all advice is greatly appreciated. Thanks guys

Says in the description 10" props. For the frame size. Them motors should be OK for them. Most pdb's now are OK with 12v & 5v output. I got a cheap SJ4000 £30, go Pro lookalike that does fpv.little bit of lag on the feed but your not racing so no worries

It's going to be tough to keep what you want in the allotted budget.

Tarot zxy-m flight controller.
Tarot t4-3d gimbal for the GoPro or like go pro.
Eachine et600 and camera combo or et200
9x5 props, but check ecalc


Here a build that I recently went through.

Note when DJI is mentioned you may need DJI style props. Look for a flat spot on the prop shaft that mates to a DJI type prop.

how do I create a Post? Sorry to use this comment to ask such a question.. But I haven't figured it out..
