Better How-To videos
The videos you post are very basic. Why not have more complex videos? If you walk us through a complex video, we would also learn the simple applications. The only reason I can think as to why all of your videos are so basic, is so that we will need to hire you to do the more complex.
Example: I want an inventory app. He should be able to look straight down a list. It would ask "how many" for each item. If the "how many" is <= the hidden "re-order" number, then it would show up on the PDF (after submitted) as a line item to order.
