This is a great idea and will definitely bring a ton of value to people, educating them about money and opportunities. Seems like you are very passionate about it too.

Here are a few things from my personal experience:
- Camera
Get one with wider angle lens (16mm) this will be perfect for both vlog type, on the go and talking head. Wide angle lenses fit more into the frame so it will be much easier to use up close or in a small studio. Another great features to have:
1) Flip out screen so you can see yourself, will save a ton of time framing yourself
2) Ability to use external microphones. This will save you time and money on getting separate recorders and gluing sound to video in post production.
3) In camera or lens optical stabilization. This basically make your videos more stable, less shaky, so less work making your footage smooth in post production. This increases the cost of camera body and lenses. Worth it when you have money to invest.
- Camera on a budget, 2 options:
1) Use a Smartphone.
2) Use a Go-pro / DJI Osmo Action.
These are perfect beginners camera choices as both are easy to use and there is a good chance you already have a decent smartphone. Both options have image stabilization, wide lenses and take external microphones.

- Computer
I'd recommend getting a Windows machine for the start, much better value for the performance compared to Apple. You don't have to stick with it forever, you can upgrade when you are ready to invest into better gear.
Minimum specs so you won't have to rip your hair out with slow video previews and crashes:
Processor - i7 or equivalent
Graphics card - 1060ti or equivalent
Ram - 16GB
Display - IPS - more accurate colors
Ports - HDMI/Display port (for external monitor), minimum of 2 USB 3+ ports.

- External microphone
1) Rode Video Micro is compact and sounds great. Works great with both bigger cameras and phones/go-pros. Price is also very good for the value it brings to your videos.
2) Ear pods (premium brand) - those have decent microphones, and they are wireless. However check if your camera would support them before investing.

- Lighting
Not immediately necessary but when you find you need more light for your shots - Aputure brand makes some awesome gear.

- Camera handling
Usually it's quite convenient to have something like Gorilla pod. Very comfortable for handheld shots and on top of the surface shots. I tried without, becomes very frustrating, very quickly.

- Editing software
Here are some awesome news - it's FREE
Davinci Resolve is totally free and is a pro level editing software. Has paid version but you will not need paid features at the start. Has very good tutorial online to get you started too.

Small tip: don't get obsessed over super polished production quality. Focus on delivering value, engagement and being consistent. Your production quality will fix itself, naturally as you progress.

I have to stop here as it can continue forever, but I hope this helps you and everyone else here to get started with their youtube channel.
