• So my hourly is £120 and overnight rate is £750 (That's probably less than ladies charge as I am an M4M escort). What do people think would be a sensible daily rate with this in mind/what do you folks charge in respect to your daily/hourly?
  
• What do people do in terms of "time off"? Presumably being at the client's beck and call the whole time would be insane
• Are there any other considerations I need to think of for these kind of arrangements?

Is he a client already known to you and you've met? If yes, I will presume he has already been screened. If not, screen him before you do anything.

For anyone who wants me to travel to them, particularly if it is overseas, I ask for a deposit of 25% to be in my account as cleared funds in order for me to confirm the booking.  Money for a taxi to/from the airport at both destinations needs to be in my account as cleared funds at least 36 hours before departure. I often ask for expenses for the airport too although to be fair, my clients tend to be generous and include money for expenses anyway. Regarding flights, as it's a long haul flight, there are two choice - either they fly me business class and we meet when I land, or, if they want me to fly coach, I ask that I have a night in a hotel at the destination by myself to recover from the flight/sleep. Flights also need to be booked within 24 hours of the deposit being paid.

In terms of pricing, personally, I charge my overnight fee + half again x number of days or overnight +7 hours, (but I usually only do trips of a few days anyway). I make it clear that I have a few hours to myself very day too, and if you want, request you have x amount of time undisturbed sleep too. One of my clients always books a suite, so I have had my own room which has been marvellous.

Ultimately, it's totally up to you how much you charge. How much business will you lose should you take x number of days off? That needs to be factored in to your fee too as you shouldn't have to lose out financially.

I also recommend you look at some of the agency websites to see their travel/fly me to you terms and conditions, it's how I worked mine out.

Lastly, how easy will it be for you to fly given there's a pandemic? Remember, you will need to quarantine when you arrive back in the UK and that means not escorting for two weeks/ten days. You might want to factor this into your decision as to whether you want to go/how to calculate your fee. 

I hope this helps!
