Dear Mr. Boyd,
I have read and studied the business proposal that you have provided me and I cannot help but be impressed with our ideas. It was presented in a clear and concise manner which I think reflects the honesty and professionalism on your part.
Because of these factors, I am glad to tell you that I am accepting your business proposition. I hope we could come together for a meeting soon so we can discuss the particulars of the business. I have also understood the details of our partnership and it was acceptable to me.
Should you have any immediate concerns, please feel free to give me a call anytime that is convenient to you. I have been in the business for a long time and I know the intricacies of starting one. Therefore, any query you have will always be welcome.
