It actually would seem rather simple to me, especially since you are claiming to have figured it all out. I.e., you have ‘correctly interpreted, currently fulfilling, time prophecies, and furthermore, you know who the actors in these propecies are, namely, e.g., Iran, Obama, Pope Benedict, etc. So why not simply give the start and end dates for those time prophecies. E.g., when William Miller, led by God, made those same claims about his panoply of time prophecies he, at the very least, gave all of his dating, and which events to expect, and that freely. Why not with this supposedly ‘timely and soon to be fully transpired, message of God’. You’re reasons thus far have not been Biblical, nor how God has worked in the past. Perhaps if you were only charging for the costs of the printing of your already printed books, I would understand. However with the internet today, all of your books and “timely” messages can be freely, a nd in their full context, be broadcast online.
Again I recommend to you the “freewill donation” approach. Who knows, if a wealthy SDA freely reads of your work and “great interpretations” online, they may be impressed to take care of all of your incurred costs during this writing effort.
