I buy camera equipment, recording equipment etc. with leftover money I make through my freelance work as a filmmaker and voiceover artist, but that doesn't pay much. Budget really isn't that much of a problem though, don't be the poor workman that blames his tools!
I'd wager that 90% of the time, big YouTubers who make videos with larger budgets didn't start with those budgets. Whilst watching their older, less professional videos may seem cringey and poor quality compared to their current stuff, it must have been good enough to catch a few people's attention for them to get where they are now!
A common misconception is that the old videos of big YouTubers only look bad because of their age, and nowadays people extent a much higher standard of production, which is true to some extent, but less professional videos still have the potential to get views today!
You just need to lower your expectations, you're never going to get a million views on a sketch that you've shot on an iPhone and released on a channel with a low subscriber count, but that's not the point. These early videos need to be creatively shot and written for the budget that you have, meaning the people who watch are more likely to be impressed enough to watch more!
If they're good enough, people will subscribe and watch more of your videos in the future, then you've got the views from the audience who came back after watching your first video, plus the views from whoever stumbles across the second in the same way that people did the first.
The budget will grow as your channel does, the early stages are hard, but you should never let a small budget or poor equipment prevent you from creating content!
(Looking at your channel, it looks like you've already got really good quality content and production value, just keep producing content, why should people subscribe if you rarely post? Keep producing stuff like what you've been doing, and your channel, and your budget, will grow.)
