Dear [recipient's name]:
I am writing to you today to notify you that when the current projects that I am managing for your company are complete, I will be terminating the services that I have been providing to your company and concluding my business relationship with you. I have enjoyed working with you for the past two years, but some changes in my business strategy have resulted in this termination.
Please do not hesitate to contact me if you have questions regarding this issue. In the meantime, I look forward to wrapping up the projects for your company that I currently have. I wish you and your stuff the best in continued success.
