Bitmine.ch; would you consider running the units yourself the first month (it will save maybee more then a week from delivery time) for your customers? You have a datacenter right?  This first weeks are essential in getting ROI with these huge diff increases. After that, a week downtime (the shipping) will hurt less.  Or they can take the managed hosting packet.

Just an idea; but it might ease the tension at little cost to you and it is profitable for customers!
