Your trip sounds very exciting! Best wishes to you in planning & executing this adventure!
Although the potential agreements will vary between providers, one certain thing is that we are paid companions. Sure, there may be some "providers" out there who would agree to going for free, yet the fact of the matter is that professional companions do indeed expect to be compensated a fair rate that is absolutely separate from general travel expenses such as flights, accommodations, and food.
Think about it... When providers goes on a two-week hiatus, they are also unable to work during that time. That being said, it is simple common courtesy to compensate them for time spent.
So.. not only do we expect to be compensated for our time, but it is also one major purpose behind our roles as professional travel companions. Gosh, I hope I don't sound like a greedy b!tch; I'm simply stating the truth.
I am not saying you won't find a provider willing to go... however if you're looking for someone who won't expect to be paid, it's just as easy to join a sugardaddy dating site or something similar.
Good luck to you in this wonderful endeavor!
