Hello Daria, How are you doing? I'd like to be your English partner. If you have interest send to me a message .:)

Here, I would either omit the "let's" and say "give me a shout" or say "let's chat" "Let's give me a shout" uses the imperative for the first person plural like saying "Skontaktujmy się ze mną"

Halo! I can help you with English if you'd be able to help me with Polish?
