History: It was a fantastic party

I'm very happy because I went to Maria's birthday party with my friends last sSaturday. That party was amazing.
I loved it because there was were a lot young people, and we danced, had a drinks, and sang a lot. I had fun.
My friends and me I arrived to the party at 12 o'clock and we gave her a beautiful present. We bought her an up-to-date clock to her to  for her new house. I met a girl in at the party. She told me her father have has a big business and he looked is looking for a secretary. I got the job and now I'm very happy because I needed to find a job.

Just a few small grammatical errors but great job! Sounds like it was a fun party.
