I am also familiar with Spanish, being a similar language, and Deutsch (studied it as a hobbie) but Im only doing Portuguese to and from English translations, as that is what I'm good at. I work on negotiable “per project basisâ€. PM me or post details and info here of your project.
Yes they are. I didn't say that they're exactly alike, they're similar in several aspects although they also have their share of differences. Portuguese, Spanish, French and Italian are all Romance languages directly deriving from Latin. It isn't surprising that if you're Portuguese or Spanish as your name implies, you can understand some bits here and there of all the romance languagues closely associated within the Mediterranean. Im sure our Scandinavian european friends can also relate within each other's comprehension, in Denmark, Norway and Sweden. But Im not offering Spanish translations because Im not fully experienced with the language nor am I a native speaker of it.
