英语,请帮我看一下下面这句有没有语法错误?
For your secondly question,the AZO free certificate will be provided if you place order with us.But it’s not official,it’s provided by our company.Is it OK?

second第二个 certificate应该是名词形式吧

secondly-second
certificate-certification

Regarding to your second question,the AZO free certificate will be provided if you place order to us.But it's not an official one but provided by our company.Is it OK?

只有一个小问题:But it’s not official, it’s provided by our company.中间应该改成句号。英文不可以这样连两个独立的句子。
可以改成But it’s not official. The certificate is provided by our company. Is it OKay for you?
对于其他人的建议:
certificate是证书的意思,certification倒不常用
second也没问题
