Any camera tips or advice for starting a YouTube channel?

So, for starters I chose on more of a blogging channel ( not much different from other YouTubers such as Conner Franta, Danisnotonfire, AmazingPhil, Caspar, etc.) but I have been stuck with a few setbacks that leave me a bit overwhelmed.

The first problem I have been confronted with is my camera choice. A few years back, I bought myself for strictly photography purposes. This camera was none other than the Nikon Coolpix L820. I spent around $200 for this camera, not including the tripod or means of carrying it in a specialized bag. I do not wish to spend any more money to buy another camera or something of the sorts if not necessary.

My second setback would be an editing program. I am not too worried about this because I do plan to buy the Adobe Premier Pro video editing program sometime in the near future and I do have experience with some video editing for friends. I have to admit, it is a bit pricey for someone who is just starting a channel (around $300 ) but I absolutely LOVE the effects they provide for your videos. Is there any suggestions of another program around the same price or possibly cheaper with equal or better quality?
