I'm sorry, my English is not very good, I want to tell you after reading your assessment of him, he would like to say thank you.
不清楚这句话的具体语境是什么,尤其这个评价是指什么,是双方见面后的印象,还是网购后留下的评价,或是别的什么。所以,我的翻译偏向于后者。
Sorry for my poor English. As a matter of fact, I just want to let you know that he feel grateful for your positive feedback left for him.
I am sorry that my English is not very well,exactly I want to tell you that he would like to say thank to you
after reading the evaluation of yours.
