You can hire us by the hour.... and you can pay by Paypal.

Basic charge for an independent production is 30 euros an hour [that includes taxes paid]. A half day is 4 hours. A full day is 9 hours, billed as 8.  

Communications and travel are considered work time. You can split an hour, but 30 minutes minimum, though we give you a break on email and telephone. 

If you want us to bring our own equipment, or work in the middle of the night, or do stunts, the price goes up.
Please note that these are rates for a production that is independent... commercial rates are higher, as are some of our other offered services. So please enquire before you budget! 
As said, we prefer Paypal ... you don't have to sign up for the service, just use a credit card. Remember, payment is in Euros, not Dollars.
