an invitation letter.

[JASMINE]

I would like to write an invitation letter to my supplier.

The content as below:
美國分公司的V.P. Mr.Jeff Mayer 會於10月1日來台。
誠摯的邀請貴司於10月2日早上9點至我司開產品會議。

Mr.Jeff Mayer V.P. of USA branch company wil visit Taipei on Oct.1st.
It's our pleasure to invitat you to haveing a products meeting our Taipei office on Oct. 2nd at 9AM.

Any grammar mistakes in above sentences?

Thank you so much for correct my grammar.

You are cordially invited to a product meeting at our Taipei office on Oct. 2 from 9 a.m. to ?????
We are happy to announce that the V.P. from our U.S. branch office, Mr. Jeff Mayer, will also be present at this meeting.

My opinion:
1. Normally we put the topic sentence at the beginning of an English article. That's why I changed the order of the sentences.

2. It should be 9 a.m. or 9 p.m. instead of 9AM or 9PM. (9後面要加space, am/pm 要小寫並加點點)

3. I'm not sure in the businsess practice whether it should be VP or V.P. or spelled out as Vice President 'cause I'm not working in a private sector. Hopefully you may get the answer from somebody else.

4. I'd suggest you estimate when the meeting will be over and put it on the invitation. That's helpful for a very organized person.

If anyone else has some other opinions, please post them on the forum. Please let me learn from you. Thanks

Carmen
