Not to be a debbie-downer, but is your priority producing content or amassing a collection of RIFs?
You say you've got 23 or so RIFs, unless they were all donations I'd say that you have had the money to get a decent camera set up. Even just a mobile with a tripod is good enough. - that's all Negative Airsoft uses, just a phone suspended by a monkey grip thing above him while he works/berates RIFs.
The best time to start anything is always 'last year or the year before'. But some get lucky in the algorithm, try and work out a niche in the airsoft YouTube world. There's enough licking shit-stains on the interwebs already.
All the best, and do it for as long as you enjoy it.
