Nah. Not gonna pay for that. Also, make sure that you have a contract for these types of paid trainings, if someone leaves within X time they have to pay part or in full the training.

Price it at your UK wholesale + VAT price and mark it as VAT 0% for abroad.

Make profit from the abroad markets, take into account FX fluctuations etc in the prices, unless the buyer is willing to deal GBP prices etc
