If you feel like you can give 100% effort on a video everyday then go for it.
Upload as frequent as you want. Do what makes YOU happy. Uploading lots of content will obviously bring more subs, but as long as you enjoy it who cares.
Nope, uploading once a day won't get you anywhere. You upload as much as your viewer base can bare. And when you just start out you don't need multiple videos a week. People will get bored of it real quick.
