Business Proposal To Handle

Hello Dear Sir/Mrs,

I would like to know if you would be interested to discuss
business cooperation with me. This is something that I would like
to discuss personally with you.

From what I understand, I am not sure if you would be interested
in business cooperation outside of your professional field.

Please respond if you would be interested in the business so that
I can send you more details.

Looking forward to hearing from you.

Kind Regards,
