"Low touch / no touch" sales is also known as "marketing." I don't know you or your intentions so this may not be directed at you, but I've found that most people looking to develop a low-touch sales engine are really saying "Ew...sales...I don't want to have to do that. Maybe if I blog enough and my site looks good I won't have to actually, you know, TALK to potential customers."
I also find that anything above about $70/month MRR is going to require talking to the person. $70 is a limit that most companies will allow to be expensed without much question. MAYBE you can get that number to $100 in the right market. Above $100? Good luck. And if you are selling a $100+ product with no-touch then you are really missing out on TONS of business that could come your way if you just put in some actual sales effort.
