Cover letter

Hello there,

My name's Barbara. I am currently working as an Event Production Assistant for a wine company event.
I'm looking for a similar job more focus on the marketing part and more precisely social media marketing.
I have found already some interesting job offers for Event Marketing Assistant for example. I wrote a cover letter and I would like to improve it. English is my second language so I need to be sure that I don't make language mistakes and have a better wording to make a first good impression.

How could you help me with this work?

Do not hesitate to contact me if you need more information about my background.

Looking forward to hearing from you soon,

Kinds regards,

Barbara
