We record all of our videos with a cell phone. I've also used lamps or clip on lights for extra light and natural light goes a long ways! If there is plenty of light, your phone should be fine, again make sure there is plenty of light. For sure good enough to get started. Depending on your video style you can use various apps to create videos. Check out the Go Pro Quik app, but there are others out there. I would also recommend, when going to buy a computer, pick up a used one off eBay or Craigslist. I know a graphic designer in town who has a 5 year old Windows PC that he was using for his full time video editing business and now it's hardly worth his time to sell for $200 or so when he paid about $1800. Something like that would be a great starter computer.
