Please Help to Amend Business Letter

I'm from a chamber commerce association.

My president gave me a task to write a letter to visit a company.
The purpose of the visit is my president would like to meet up with the director of the company and discuss/talk with him/her.

Would like to be in a formal letter.
Really hope you can help me out with this. Really had no idea to make it more attractive and proper way.
Sorry for my bad english

Below is the draft letter.

Besides that, I would like to put in the dates, where should I put it in?
For example:
Wish could make it at Feb 4,5,6,10. Is your director will be free during this dates given?
or
Do we need to make an appointment or we can straight visit your company and meet up your director?
