Thank you so much for your answer. I do understand all your concerns.
What can I say about the editing, the result is pretty much depends from the initial picture. And as it was only I test work I was not able to show You all, what I can. I pretty much sure, that I can provide You the same quality as on example.
The other question is a price. I am ready to talk with my Boss about other numbers, but you have to give me some start point. What kind of price is ok for You?
