“很多年前就听过贵公司，并知道贵司是一个很有实力的公司”英文翻译是什么？

I have heard of your company many years ago,
and I also knew that the company is very strong.
一般英文说很有实力，会提及是哪方面的实力，建议你可以考虑~
譬如说：
...and I also knew that the company is very strong in finance industry.
（在金融界很有实力）
...and I also knew that the company is very capable of creating new ideas.
（很有实力去创新）
