I just checked ya out... You have a lot of subscribers and past videos have nice views!
I have to be honest though, it seems you need 3 things: a microphone, better backdrop( maybe use green screen in future), and a 5-20 sec long intro.

Here is a site that will help you out a lot.

You have the audience, though old at this point and need to reconnect since its been years, You have the history of great views and overall a youtube channel that is already built for success. You have immense potential my friend! Check out https://www.splintertalk.io/@bulldog1205/ and his videos to see what I am saying.
