First off welcome to the community. I don't know if the author of this thread will answer (the date's almost a year ago), but I will.
We've done a good number at Quest and find that good video takes either time or money. We don't have any of the second, so we take the first. To paraphrase Tone, "You can pick any two from the list, but not all three: high quality, quick, inexpensive." So to answer your question, I could do two a day with the right staff and equipment (money). Or I can do one every couple of months with very little money.
As to equipment, we use a first generation iMac DV with Final Cut Pro 3.0 and a Sony digital camcorder and get great results. A light kit and a 3ccd cam would help, but time and imagination help a lot.
