Help me with my graduation please! Spanish

Hi!

I'm gonna graduate soon, and I have to give a small presentation in spanish,

and i was wondering if someone can please help me, by checking  a document (only 1 a4) on major spelling mistakes and some grammar which might be wrong. Just checking if it would be understandable if i would present it.

I can help also with English, Germand and Dutch, as I  speak those languages fluently.

Thanks in advance!  :)
