Translation from English to Portuguese

I have most of the design completed for a chatbot app. I'm looking for someone with actual experience to now take the basic foundation I have and finalize this into something that can be delivered to a full stack developer. Should include things like refining existing pages, adding missing pages, updating branding, etc. Will require a bit of collaboration.

This should be a relatively quick process but if this is a successful venture I would love to turn it into a more long term partnership.

Thanks in advance.
