If you want an estimate without contacting me, I can give you a number of 100 euros/hour. This number varies on task, location, additional expenses and level of retouching. This amount is just for my services - no make-up, rental or other services are included.
If you are foreign client, 100% deposit is required unless there is signed contract with all the bells and whistles. Local clients - well, it all depends - for the first time work 50% deposit is a must and another one after you have previewed the result of out collaboration. For that, you receive personalized, password protected link with images.
I am registered tax payer in Latvia, EU. If we are working together you do not have to consider any extra taxes to be payed for my services /I pay them upfront/. Of course, things may vary.
