In your current product lineup you are competing for the academic and church staff/organization markets. Yes, you are doing well in them but there are competitors who also appear to be here to stay. However, there is one very large under-served market you could easily move into. I normally refer to it in terms of lectionaries or dated items but this year I'll address it via undated items.
Think for example of some of your workbook like resources - Wiersby or Lucado. Now think of a demo video of a religious ed class or small group in which
- Participants use the text, a Bible and FSB on their iPad or IPhone.
- The teacher has provided a reading plan consisting of 1 lesson per week
- The participants enter their answers via Logos text boxes
- The teacher encourages use of community notes by seeding the notes with appropriate examples
- The teacher & participants use the Discussion area for discussions that spill out of class
You could consider giving "scholarship" copies of the text when an organization provides x numbers of orders.
You could consider joining with Church publishing houses - advertised in their catalogue as well as your own - for dated materials with "automatic" reading schedules [think SDA as a potential target ... Abingdon and Cokesbury also come to mind].
While the individual's initial investment would be very very small by your measures, they would form a market with a continuous stream of purchases .. at least one for each new class. They would be a prime target to slowly add Bible translations, Bible dictionaries etc. ... and they would be predisposed to look at Logos when and if they ever want a serious package.
Yes, there are a few enhancements needed to text box processing to make this work but you have most the pieces if you simply try them out (attempt to make the video and identify the potential error) do a bit of tweaking and target an audience. A few success stories and you should be off and running. Even my never-used-email 75 year-old sister-in-law has gone iPad!!
