Dear sir,
I am a biology teacher in a university. Nowadays, a lot of laboratory equipments are needed for students to get a high level of education and acquire world knowledge. At the same time, we want to produce microscopes for schools and universities.
So we need $3000 from your bank. For this money, we will bring the necessary spare parts for the microscope from the usa. For example, it includes important parts such as the eyepiece, objective, and object table. We make 10,000 microscopes and sell them to schools and universities in one year.
Of course if our plan comes true. We will return the $3,000 we took from you within 2 years. We would like you to help us.
Thank you for reading my message. We hope you will agree. Thank you for your attention.
