Hello.
As a brazilian translator, I would be glad to help you with your proofreading.
I worked for a few months translating adult content. My job was translating video descriptions and its titles. So I believe I have the knowledge to proofread your text. I noticed there are some tiny problems in this translation. Somethings that could be changed to become more clear. In Portuguese we have a diferent grammar and concordance structure to make clear what we want to say.
It's a short job so I can do it in a few minutes.
Please, if you have any question about this proposal, feel free to contact me.
