Not only are businesses not alienated by this sort of thing, many of them will either a) have explicit budgets for it or b) have explicit requirements that they cannot buy your stuff if they cannot also buy the training.

An Appointment Reminder customer wanted a quote for training. I said "Do you want me there to lead an in-person training session, a webinar, or several videos showing operation of the software which your team can review at their leisure?" She said "Quote me all of those." I think I picked $10k, $4k, and $2k. She said "Hmm -- no need to fly you out here but we can greenlight either of the other two without needing to talk to anybody."

(n.b. Assume that the yearly contract for the service itself is in the four figure region. That sometimes matters -- a few companies will just automatically assume support/training costs 20% of invoice.)
