Hello,
As recently saw in this topic, I came with the idea to release a free exchange service for translations.
We are here to help each other in making money and win relevance within Play Store. For that reason I’ll be able to share translation in Portuguese language for everyone that would like to have it. Hope you can do the same for other people (inclusive me in a near future) 
You can earn a lot with a good and human translation. My English is not very good, for that reason I’d like to have someone too who could “correct” my Play Store text from common mistakes.
So, for a reason of functionality, what I Offer?
- Portuguese Translation of Any Text for Play Store. Please note that after Portugal, there are other countries where is being used Portuguese Language as Brazil, Mozambique, Angola, Guinea-Bissau, East Timor, Equatorial Guinea, Macau, Cape Verde and São Tomé and Príncipe with a potencial reach market of more than 270 million users.
Service Price: FREE
Language for Translation: Portuguese
So what I need to be sent:
Change App Name: Yes/No ( Send app name if you wish to translate it )
Change Localized Graphics Text: Yes/No ( Send the me sentences you have in your graphics and I’ll put them in Portuguese too and you can upload localized graphics )
Change PlayStore Description / Text: Required… 
I’ll not make ASO on my translation. If you want to, you can see the keywords you would like to use in Portuguese ( for example if you have a racing game and want to use the “Velocity” word, just send me that word as keyword and tell me how many times it should/could be repeated and I’ll change the play store text a little bit to fit those keywords ).
Let’s help each other
