Ian Guides a WW1 Battlefield Tour - Maybe? (Patreon)

So, I have another question for you folks. The guys at Military History Tours have asked if I would be interested in creating and guiding a tour of my own. It sounds like a really cool idea, and a fun and rewarding endeavor. That said, it would need to be something that would actually appeal to people - I would want to have 15-20 people to make it practical. 

My concept for the tour would be an overview of WW1 from the French perspective. I think a lot of people may not want to admit it, but don't really know much more about how WW1 progressed than "lots of trenches and then the Allies won". So the tour would take 1-2 days for each phase of the war, showing a combination of the big picture of how the war was fought progressively through the conflict and also human-scale anecdotes of the action. Specifically:

1914 - The Marne/Frontiers. Mobile warfare and the near fall of Paris.

1915 - Trench warfare. Stagnation without innovation.

1916 - Verdun (and the Somme). New tactics truly industrialize slaughter.

1917 - Nivelle offensives - the Chemin des Dames. Armies reach the breaking point.

1918 - German collapse and Allied victory.

The cost would be $3000-$3500 per person, plus you cover airfare to get to France and back. It would include about 2/3 of meals and all lodging and site admission fees. We would be going to one or two museums and monuments, and mostly battlefields and forts. 

My question is, would people be interested in such a tour? As in, actually willing to pay for it? I don't know if this subject is one that would be interesting enough to fill up a tour. This would most likely be in the autumn of 2019. If the subject is not interesting but there is one in Europe that you would legitimately be willing to pay to join, please let me know what other topic would be of interest.

Thanks!
