There are several native EN>SP translators (me included) with high rank and proven experience in the Local section of the forum, and I guess it is the same for Portuguese, who will be more than happy to offer their services at discounted market price.
These 1 Bitcoin translations from a brand new account make no sense
Potential customer, I won't warn you about the risks because if you are willing to pay 1 Bitcoin then you are already rich and can do whatever you want with your money
