I will be glad to help you with the translation into Russian, because you list Russian in the requred skills but you do not say anything about it in the description. So, If you need a Russian translator I can help you out, but if not, then I'm sorry. However, I do not speak Potuguese, meaning I can only help you with translating English into Russian and vice versa. I think 10 dollars for a page is a very fair price, if you are interested, you know what to do, just sent me a message and we can talk about it. But I would like to know the theme of the text and how many pages of it do you have (I bid for 25, but I can change it if you wold like me to translate more), Hope tohear from you!
