I'm starting out doing one video a week. It seems sustainable to me, and it allows me to "get ahead", just in case there's a week where something pops up that might prohibit me from uploading. Right now, I've got a month's worth of videos produced, edited, uploaded, and ready to publish on a weekly basis. I let my schedule be known, right in my banner ad, so viewers know to expect a new video every Friday. My thinking is that if I'm able to produce content at a faster clip, without making too many sacrifices, and without sacrificing time with my family, I'll increase my publishing frequency. For now, once a week seems to be working.
