Help me

Hi, my name is Ubaldo and I need urgent help with my English. It is terrible. In return, I offer perfect Spanish.

Notes about my corrections: you have 4 ideas here. 1) your name. 2) need help. 3) your English is terrible. 4) you offer Spanish help. Idea 3 needed a noun so I put the pronoune "it" (that is your English). I put a comma after the word 'return' because that part is an introductory phrase - it introduces and get's your reader ready for idea #4. And every sentence with a noun and verb must end with a period.
