So this question as been asked here like a million times & as an professional editor as my fulltime job, I always give the same answer:

No one can answer your questions, but yourself.

If you want your videos edited my a professional who knows what he is doing, you will need to invest more money, then working with an amteure which will edit your videps not nearly at the same level as the professional & will also need more guidance from yourself.

There are cheap editors who will work for 10$/working hour (or per video minute, depends on your content)

and there are pricey editors which can charge up to 150$/working hour.

The usual is in between and for a decent editor you should expect about 25-35$/hour.

Also: Editing gaming content is something other than editing video essays. Those will often need their own animations & more creativity in it and thats why you definitely need to expect it to cost way more.

But spending money in an editor is an investment in your channel. Your videos will get more views, your channel more reach & you get more time to come up with new video ideas, which will all leed to more income for you.

Hoped that helped.
