请问该如何去向外国人介绍自己公司的产品呢？

Do you want study Chinese?(你想学中文吗？)
We are study Chinese of school!(我们是学中文的学校)
说是能说通，但不知道第2句对不对，我也在学英语，第1句是绝对不会有错误的

We are one of the largest computer manufacturers in our country and have handled with the products for about 10 years.We approach you today in the hope of establishing business relations with you and expect,by our joint effects,to enlarge our business scope.

My company is a Chinese language training organization which aims to help foreigners learn Chinese (mandarin/cantonese) effectively.

yeah!!~~
