How to write business letters

[Limon]

Dear Teachers,

I’m in trouble I don’t know how to write business letters at all. Would you help me ‘translate’ the following letter into a formal business letter?

Regarding your e-mail of March 24, you indicated the possibility of your visit to Japan after the visit to New Caledonia in May.
I spoke to the parties concerned in Company A and Company B, and if circumstances permit, we‘d like to have a meeting with you and approximately ten parties concerned. So please let me know a convenient date for the meeting, One day would be enough for the meeting. If you wish, we’ll show you around in Tokyo.
