You can email me with a description of your request and the date when you would like to meet.
You can call to discuss about how I can respond to your expectations.
You can also text me by SMS or Whatsup to explain your objectives.
I will give you my terms and conditions by mail or by text message. Minimum is 2 hours. But I can do overnight in Paris. Or I can even travel to you if we have met before.
Looking forward to meeting you.
