Well well dear A & C, doing some advertisement work?
With us pilot get everything they need starting from 50£ an hour in USA.
We've also thought to go with a cheap formula operating something in Europe, but VAT kills you anywhere.
If you are operating professionally in Europe, there is no way you can avoid letting your customers pay for VAT (unless you work with partial ownership schemes), otherwise you would be operating illegally. You may encounter problems with your insurance company if any incident/accident happens on one of your aircraft.
Let's not forget to mention the expensive landing fees that you won't pay in the US and the fact that though you are based in the UK, UK students will need to get to your aircraft, be it by own means or by public transportation.
On the other hand you save yourself alot of paperwok (visa+FAA) which saves you alot of time and money.
There are advantages and disadvantages everywhere.
